Visual studio shortcut keys / settings

These are the ones I keep forgetting about:

• Enabling line numbers: Tools, Options, Text Editor, All Languages, Show Line Numbers (source: http://stackoverflow.com/questions/5905687/can-i-see-line-numbers-in-the-vs2010-editor)
• Toggle whitespace/tabs: CTRL+R, CTRL+W. (source: http://stackoverflow.com/questions/4065815/how-to-turn-off-showing-whitespace-characters-in-visual-studio-ide)
• Navigate cursor to previous+next position: CTRL+- and forward CTRL+SHIFT+-.

These are a few you can't do without:

• Step into function: F12 (CTRL+- to return cursor to previous position)

If you can afford it you can't do without Visual Assist X either.
