Text editing: switch to Override mode In insert mode, the text in front of the cursor is pushed forward when new text is inserted. For example, if the cursor is at position ^ and the word word3 is typed:

word1 word2
      ^


The result would be:

word1 word3word2
           ^


In override mode the result would be:

word1 word3
           ^


Can I switch between Insert mode and Override mode in OSX text editing?
As far as I know, normal OS X text views don't support anything like that.

In TextMate 1 you can use ⌥⌘O (Edit > Mode > Overwrite Mode).

In Word 2011 for Mac you can go to View > Toolbars > Customize Toolbars &amp; Menus and drag Commands > All Commands > Overtype to a menu.
