> Coming from OS X Also, do Windows editors have that Alt+drag rectangular text selection feature that most/some OS X apps have?
No, it is implemented by each editor/ ide independently with their own modifier. On the contrary we have mostly consistent ctrl/shift + arrow behaviour over the last 15 or more years(I don't know before that). :-)
Are you saying Windows has consistent Control/Shift + arrow behavior?
OS X is pretty consistent about this too, though Control+Arrow moves between Desktop Spaces, not related to text, but you can modify a lot of system/app shortcuts from Preferences -> Keyboard -> Shortcuts.
