I extensively use the two-finger tap, two and three-finger tip-taps on my Magic Mouse to replicate similar functionality or semantics throughout apps.
In mail for instance:
- two-finger tap: archive
- tiptap middle (2 fingers fix): delete
- tiptap left (1 finger fix): reply
- tiptap right (1 finger fix): forward
This becomes the baseline for all apps, two-finger tap approves, validates, archives whenever I am, while tiptap middle (2 fingers fix) refuses, deletes, trashes wherever I am.
This has proved incredibly useful with Word. I use the tracking changes mode extensively (I’m a fiction writer) when going through novels with my editor. (Some chapters see two to five distinct passes and I write 800-page long books - that’s a LOT of changes and comments.) I have bound the tracking changes commands to specific keyboard shortcuts which are then fired through BTT gestures:
- two-finger tap: approve modification
- tiptap middle (2 fingers fix): refuse modification
- tiptap left (1 finger fix): add new comment or reply to comment
- tiptap right (1 finger fix): delete comment
Also a very simple one I have is command-clic bound to a single tap in Safari. Allows to open links in new tabs with a simple tap of the mouse (the way middle-click works on Windows browsers).
