  • Keyboard shortcuts have changed without my sense to-cannot use important keys

    Hello.

    This morning, out of the blue, two important keys on my keyboard are not what they are supposed to:

    (1) shift and the letter 'c' launches an application on the computer instead of allowing me to type a capital "c". I am a writer and cannot continue without the ability to take advantage of this letter.

    (2) my "Tab" key is no longer allow me to move around in a document (from cell to cell in Excel or Word from the tab to). It is now to move from the application.

    I've exhausted my investigative efforts and may not know how to restore the keys on the keyboard to their original functions. Help, please!

    Thanks in advance.

    First step with a problem like this (or most of the problems) must be
    to restart the computer. It sometimes fixes things. Have you tried?

    If this does not work, buy or borrow another keyboard and see if you are using
    This solves the problem.

  • How to set the pressure necessary for the keys on the keyboard? I adjusted it 2 years when I had my Macbook Air, but I forgot how I did it. In my opinion, only a touch of F has been used.

    I don't know what you are referring. You can't 'adjust the need to pressure for the keys. The keyboard is what it is. The key must be pressed far enough for electric contact in key switches. The keys are not adjustable in this way.

  • slide show by using the keys on the keyboard for nav in flash professional CS5 with animated images

    recently, I discovered how to create a slideshow using the keys on the keyboard for the market front and rear in flash professional CS5 thanks entirely to kglad of this forum. I used still images for each slide, since, then with one of the slides, I added a slight undulation of water in one of the images in a separate document. is it possible to include this file in my slideshow now?

    I'm a graphic designer who has a presentation of my portfolio. I'm not too experienced in flash and do not use it much, but he needs to do this on the thing. I can do a fade in and out slide show, but I want to create a slide show where the screen remains out of the blade and does ' t until what I press the next or previous button. I don't want these keys on the screen, I want to be able to press a key on the keyboard as F1. is this possible and do you know in adobe flash Professional (or other adobe products) where I could get resources/tutorials to do. Any help so what would never be great.

    create tweens to fade for each slide.  You'll probably want to fade out the image on image 1 (from frames 1 to 11).  Bland-in the image of frame 11 frame 1 to 11.  fade the image frame 11 11 to 21 etc.

    You can then use:

    var image: int = 1;

    var dir:uint;

    stage.addEventListener (KeyboardEvent.KEY_DOWN, downF);

    function downF(e:KeyboardEvent):void {}

    {if(e.keycode==Keyboard.Left)}

    dir = Keyboard.LEFT

    Frame = Math.Max (Frame-10, 1);

    this.addEventListener (Event.ENTER_FRAME, nextF);

    } else {if(e.keyCode==Keyboard.RIGHT)

    dir = Keyboard.RIGHT;

    Frame = Math.min (this.totalFrames, Frame + 10);

    this.addEventListener (Event.ENTER_FRAME, nextF);

    }

    }

    function nextF(e:Event):void {}

    {if(dir==Keyboard.Left)}

    prevFrame();

    } else {}

    nextFrame();

    }

    {if(this.currentFrame==Frame)}

    this.removeEventListener (Event.ENTER_FRAME, nextF);

    }

    }

    you have the fla that created the swf file?

    If so, just copy images from this fla and paste into a new movieclip in your fla slideshow.  Add this movieclip to your timeline.

    the best way to do what you want (but not the most flexible/changeable) would be to add each slide a key frame to its own layer.  It is a design decision, but start with keyframes at 1, 11, 21 etc.

  • by using the key on the keyboard in forms

    Hi all
    I want to create a form like this...
    Suppose that a textbox control is there when I run the cursor of the form is on the text box to this moment I want to press the F8 key to the
    keyboard to fill the lov with empno, ename from emp table
    When I tap on the lov say empno 7369 then it should appear in the text box without pressing the ok button on the lov
    and at this time, when I again press F9 on the keyboard then the lov should appear as the opposite of the previous ename, empno
    then I Pat that assume the name of scott and it should appear in the text box.

    I'm working on forms of oracle 10g...

    How to do this...

    Suppose a textbox control is there when I run the cursor of the form is on the text box to this moment there I want to press F8 on the keyboard to complete the lov with empno, ename from emp table

    Depends on your current key-mapping. If you use the 'classic' client-server keyboard mapping, then you can use KEY-EXEQRY-trigger to your article (it fires on F8)

    When I tap on the lov say empno 7369 then it should appear in the text box without pressing the ok button on the lov

    This standard behavior, just set the 'Automatic Selection' property on the 'Yes' to the LoV

    and at this time, when I again press F9 on the keyboard then the lov should appear as the opposite of the previous ename, empno

    Why again? It is F9 or is it a typing mistake. Lets assume that it's F9. Create a second LoV with different order of the columns and add a KEY-LISTVAL-triggerto your article to which you attach this new LoV using
    SET_ITEM_PROPERTY ('THE_ITEM', LOV_NAME, 'THE_NAME_OF_THE_LOV');

    then I Pat that assume the name of scott and it should appear in the text box.

    Once again, norm behavior, just the value of the property 'Automatic Selection', 'Yes' to the LoV

  • Key on the keyboard does not work in firefox box when you type in the web site, but it works everywhere else?

    Key on the keyboard does not work in firefox box when you type in the web site, but it works everywhere else?

    Try Firefox SafeMode to see how it works there.

    A way of solving problems, which disables most of the modules.

    (If you use it, switch to the default theme).

    • You can open the mode without failure of Firefox 4.0 + by pressing the SHIFT key when you use the desktop Firefox or shortcut in the start menu.
    • Or use the Help menu option, click restart with the disabled... modules while Firefox is running.

    Do not choose anything at the moment, just use 'continue in safe mode.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before using the shortcut of Firefox (without the Shift key) to open it again.

    If it's good in Firefox Safe mode, your problem is probably caused by an extension, and you need to understand that one.

  • Satellite A300-15J - keys on the keyboard

    Hello

    I got my laptop about a week now. I liked it carefully, the brilliant keyboard did irritate me at first, but... But to my surprise... this morning the left low corner command button was loose... it seems that one of the "connectors" broke up.

    Of course, I know what to say, I broke it, and it's probably true, because I type on my computer and so to put pressure on it... BUT, I have a respect for computers, I don't hit my computer and I have typing skills...

    I called a local computer company and they said that I need to replace the entire keyboard... because Toshiba will probably not fix it under warranty because they will say I did damage... I had a toshiba A100 for 2 years, the keyboard still works fine...

    I wonder if anyone has any suggestions or comments on this topic?

    Thank you very much.

    Well... sad story, but the fact is that the key on the keyboard is broken and the keyboard needs to be replaced.
    I don't know why it broke... maybe you used really too much pressure while typing... who knows. ?:|

    I have two Toshiba laptops different... one is 5 years old and the other is about 2 years old and I never noticed any problem keyboard or buttons...

    So in my opinion, you had a bad luck... that's all.

    Good luck with your keyboard replacement...

  • R850-169 - key on the keyboard to replace satellite

    Hi, I dropped my iphone on my laptop (of less than 30cm, I might add) and in some way he hit the right CTRL key and the key on the keyboard is popped! a whole little plastic broke from under the key (the mount under the white key is fine, just the black key is damaged)

    I was basically wondering. Is there anywhere you can get replacement keys for this laptop?

    Theoretically, you can try to find the defective keyboard, remove the button even CAP and set up on your laptop keyboard.
    To be honest I don t think you can buy these caps key as unique pieces.

    Check ebay. Maybe you can find defective or used the keyboard for a few euros.
