I'm using MS Word 2011 on Mac OS X but I assume that it's got very similar functionality to its Windows counterpart.
If I delete a word in MS Word (using ctrl-delete on Windows, and cmd-delete on Mac), then MS Word typically deletes the space preceding that word, as well.
How can I stop MS Word from doing this? I'm not used to this so I rarely re-add the space myself, since MS Word is the only application to do this.
