Intellij: Code highlighted purple in debug mode

Does anyone know what this purple highlighting means in Intellij debug mode?
Immediately after executing this line in the debugger, the program exits with no error message or error thrown.
This is called "Smart Step Into", and allows you to select the method, that you would like to step into for debugging, if there are multiple method calls in a line (like in your example). To use this feature, you would press Shift + F7, and then either click on the method, or use the arrow keys or tab button to choose the method, and then either press Enter or F7 to enter that method.

How to activate the cursor in VS2010 after pressing Ctrl-Tab?

When you come from a tool window and press Ctrl+Tab to go back to an editor window, the cursor is gone and replaced with a "line cursor" that only allows to scroll up/down but not enter text. Is there a key I can press to get the normal cursor back?
(This is especially useful to quickly compile my code Ctrl+F7 and then just type on after pressing Ctrl+Tab without having to click the mouse)
Press Ctrl+F6 instead of Ctrl+Tab. This brings you the editor you last typed in with the cursor at the latest position.

How to use "marker" in R-studio

I found that by using mouse click, we can create a red dot as a "marker" in R-studio. This is very nice. But how to simply go to this line with a marker?
I use SAS also. In SAS, it is like pressing Ctrl+F2 to create a marker, and press F2 to go to the next marker.
Anyone use this before? Thanks!
That isn't a marker but rather a breakpoint. When you run a script with a breakpoint, execution will stop there. Unfortunately there isn't currently a way to jump to breakpoints.
You can get similar behavior by inserting sections: use Code -> Insert Section to add a section, then Code -> Jump To to jump to any section quickly (there are hotkeys for these as well).

ConqueTerm bash in Vim, key input delayed

I've just found out that I can use ConqueTerm to bring up a terminal window in Vim. But I have an annoying issue regarding this.
Lets say I go into insert mode to type commands, and then want to exit insert mode, it will not work unless I press Esc key and a different key. It seems to be a set timeout or delay of some sort. Symbols and characters show up in the bottom right corner of the terminal window.
I had the same problem when editing files in vim, but added "set timeoutlen=1000 ttimeoutlen=0" to my .vimrc which sorted this out for me. But I've been looking around and I cannot seem to find anything similar for ConqueTerm. My guess is that something is to be put/edited in "~/.vim/autoload/conque_term.vim"?!
Any help would be most apprechiated!
Thanks

Xcode - stepping over the debugger to cursor location

Is there a way to to step over the debugger to the cursor location?
In many occasions I want to skip a whole section of code while debugging, in that case I have to put a new breakpoint in the line I want to go to and click the continue execution button. I can't believe Xcode lacks the step over to cursor function.
Right-click on the line and select "Continue to Here".
If you move the cursor over the line number a little icon comes out that is a little play button That lets you run the code and stop at that selected line. Give that a try.
