I installed the Visual Studio 2010 productivity power tools, and since then Shift + Enter does not add a new line in the text editor. I've tried disabling all of the productivity tools settings and even uninstalling the productivity power tools entirely, but Shift + Enter still does nothing. I can't find the setting for this.
How can I re-enable shift + enter to add a space (just like enter alone does)?
In new versions it was changed to Ctrl+Shift+Enter, And you easily can change it as sbi suggested
Try Ctrl + Shift + Enter to add a line bellow.
Ctrl + Enter will add a line above.
From Options menu, select "Environment", then "Keyboard" that gives you the option of setting keyboard shortcuts. The one you want should be "Edit.BreakLine" - you can search for them. Selecting this, you can then add/remove assosciated shortcuts.
Tools/Options/Environment/Keyboard
.Edit.BreakLine
command.Press shortcut keys
edit pane press Shift+Enter.
