Hi,

on the topic of wheelmice... actually it's a new feature so I'll ask before=
=2E=20
The attached patch makes konsole pass wheel events on to the terminal app=20
when in mouse mode. This enables e.g. wheel scrolling in vim.
It *could* also be seen as a fix to make konsole more xterm-compatible *g*
