dstein64 created an issue (vim/vim#16905)

Steps to reproduce

vim --clean
:set mouse=
:help builtin.txt
" Rotate the mouse wheel down

Expected behaviour

I expected that with mouse=, Vim would ignore mouse wheel events.

Rather, the cursor moves in the direction that the mouse wheel is rotated.

Version of Vim

9.1 (included patches: 1-16, 647, 678, 697)

Environment

Operating system: Kubuntu 24.04
Terminal: Konsole 23.08.5
Value of $TERM: xterm-256color
Shell: GNU bash 5.2.21(1)-release

These are not mouse wheel events but keyboard events. They are
generated by your terminal emulator.

To see this, with Vim configured as above, enter insert mode and
type Ctrl-K followed by a rotation of your mouse wheel. You should
see <Up> or <Down> for each click of the mouse wheel. Those
correspond to your keyboard's up and down arrows. Type Ctrl-K and
either the up-arrow or down-arrow key and you'll see the same <Up>
or <Down>. You'll need to type Ctrl-K before each mouse click and
key press.

Regards,
Gary
