Tip: TextMate Overwrite Mode
Posted by anthony crumley, Sat Nov 24 08:10:00 UTC 2007
Overwrite mode does exactly what it sounds like. It overwrites existing text as you type. When in overwrite mode the caret is an underscore. Option-apple-O toggles overwrite mode on and off.
I don’t use overwrite as much as I should. I find myself using the delete key way to much. Often I will delete a bunch of text then type something in its place when overwrite mode would have eliminated the delete step. Next time you find yourself doing this, try switching to overwrite mode and save your delete key some grief.
