vim with set mouse=a, shift click causes scoll down

[squalou]

Hi,

usually when using set mouse=& in .vimrc, holding shift and left click will allow to copy text. (not to vi buffer, but to general clipboard buffer).

When doing so in cosmic-term, shift click will scroll down a few lines.

I didn't find what shortcut I may have broken on my side, would be interested if someone can reproduce.

thanks !

kind regards
