[Chimera-users] scrolling

[Elaine Meng]

Hi Matt,
If by “zoom on the trackpad” you mean two-finger scrolling, you can turn that off in the Chimera Preferences opened from the Favorites menu.  In Preferences, go to Category: Mouse, set “Use scrolling” false.  If you mean Mac gestures like pinch or the opposite, that is also in the Mouse category of Chimera Preferences.  Remember to click Save to apply these preferences to later uses of Chimera, if they seem to do what you want.
I hope this helps,
Elaine
