Trying to move between screens in screen. I press Ctrl-C then the screen number I want. It doesn't work and the top of the screen says "copy mode aborted". What's happening?

Num Lock is off. It's as simple as that.

Lost my toolbar in Jgrasp how to get it back?

lost my toolbar buttons in Jgrasp I accidentally clicked the "X" button on the thought it was the exit button checked settings but too afraid to click a button that will change the environment again, here's the result,
Thanks!
The toolbar is language specific, so the toolbar goes away unless you have a file open. Since you pressed the X button, the file was closed, and thus, the toolbar went away. If you open up a new file (By clicking the folder icon on the far top left and selecting the previous file), it will bring back the toolbar.

IntelliJ Idea: how to dock the java-doc window

how can we dock the java-doc window to the IntelliJ IDE?
There is no Docked mode in the window-popup like explained in the IDE help
e.g. it should be like the Structure, Messages, Version Control tool Window.
Yes, there is something wrong with this window: by default it shows up in your face, preventing you from getting any work done, and it is not immediately obvious how to dismiss it. A programmer's first encounter with this window tends to be a rather bad user experience.
The way I dismiss it is as follows:
Click on the gray gear menu (the one at the top, not the blue one right below it)
Uncheck Floating mode. It will then obtain a "Docked Mode" option.
Move it to any side you like; it will then stay there.

How do I resize the window of screen?

Just got into using Screen for remote pair-programming purposes with Vim.
Was wondering if there was a way to resize the windows as our terminal space is somewhat very limited with the default settings.
Currently I'm getting into screen like this:
User 1: screen -R test
User 2: screen -x -R test
Most of the time screen will simply resize the windows it owns whenever you resize the terminal emulator that owns the screen session.
However, when someone connects to your screen session and your screen is wider or higher than that person's you or that person can use Ctrl+a F (uppercase F, i.e. with Shift held down) to adjust the size of the current window (inside screen) to that of the terminal emulator in which screen runs.

App crashes when tapped frequently

I am working on an app for iPad. In one class, I have used a scroll view at the bottom of the screen. This scroll view has some buttons. Those button play a video or open a PDF file. When user frequently taps on those button the app crashes. I have no idea why is it happening. Can any one please tell me why is it happening and how can I fix this crash?

You should track the state of your view. Which button was pressed last, and don't allow it to be pressed again until.
a) it is done loading the pdf/video
and/or
b) another button has been pressed
You might have to be more strict than that, but we cannot help more than that at this point as Till mentions in your comments

Cocoa documnt based app does not do anything on Command W

I would like it to close on Command ⌘-W as per the standard. There is a close button on window and it's enabled so I'm not sure what is eating the close command keyboard shortcut.
The content view is a webview if that makes any difference.
I've implemented windowWillClose and windowShouldClose but none of them are hit during debugging when pressing Command ⌘-W.
Does the File menu at the top of the screen flash when you press Command ⌘-W? That might indicate whether something is eating the key event before it goes to the normal responder chain. For example, I believe it is possible for some javascript in your webview could be eating the event.
Normally the Command ⌘-W is sent to the firstResponder (usually the control where keyboard focus is) and then along the responder chain. This document might be helpful: http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/EventOverview/EventArchitecture/EventArchitecture.html%23//apple_ref/doc/uid/10000060i-CH3-SW10
Some things to try:
Make a text field outside your webview and see if Command ⌘-W works when that text field has focus. That might implicate the webview.
Turn on NSObjCMessageLoggingEnabled.
This produces lots of output, but can show you exactly what methods are called after you press Command ⌘-W.
