I just discovered you can use CTRL-Tab to tab through windows within an application. Things like workbooks within Excel. Or tabbed browser windows within Firefox.
This is fiddly, but I’m pleased that there is at least some kind of shortcut.
You knew this one? Oh ok. It was news to me. And I found it just by a slip of the finger on the keyboard!
Another one that people often don’t know about is F2. In Excel or Powerpoint or Explorer, hitting F2 allows you to edit the text inside something. Be it a cell, a shape or a filename.
What does this have to do with user experience? While I work on a posting about it, why not try using the shortcuts for a while and see what you think.
