Hi Thomas,

yes, with mouse over the scrollbar the problem is reproducable.

A blind key is a key that needs to be followed by another key to produce something.

The problem here is, when running vi in an xterm and the mouse slowly (unnoticed)
moves over the scrollbar or out of the xterm, and you want to jump to mark "a,
you need to enter `a, that is in keystrokes
1. blind key `
2. space
3. letter a,
the bug will drop the `, so you will not end up with the cursor at mark "a, but
you will move the cursor one character forward and there enter append mode.
Which is something totally different than the intention.

Or if you type :%s/^x/y/
You will really get :%s/ x/y

Hopefully you notice it before pressing Enter ...

Exaples refer to a German keyboard layout.

Thank you for looking into this.
