I'm a heavy user of the keyboard and I've noticed this toolbar appearing from time-to-time when I'm typing a message in Outlook
- What is it?
- What key combo have I pressed to get it to appear?
- Is it useful?
- Can I turn it off?
If I press Esc, Outlook unhelpfully offers to discard the entire message for me which is not my intent here. I need to remove my fingers and mouse this one closed which I don't like or want.
