Is there a way to change the hotkeys for tool modifiers? Such as when I am using the brush tool, I can easily change the opacity by pressing alt + a number (i.e. 5 for 50% opacity). The control key is now designated for flow, which is my favorite brush moderator, however control is also used for Mac's spaces toggle. If I press control + 2, my desktop switches over to space#2. Using the control key is deeply ingrained in my head to toggle bewteen desktop spaces, so I do not wish to change that preference if at all avoidable. I have checked my keyboard shortcuts but cannot locate such a preference. I also do not wish to create a brush preset becasue I like to toggle brush flow very often.
UPDATE: I am a fool. Simply typing numbers can toggle flow, no opt or alt needed.
