Mouse - otfried/ipe-wiki GitHub Wiki

Find the file mouse.lua in your Ipe Lua code directory. You can find this directory by going to the Help->Show Configuration menu option in Ipe and noting the 'Lua code' directory. It will be something like

Lua code: /usr/local/share/ipe/7.0.10/lua/?.lua

Copy that file to your personal ipelet directory (e.g., $HOME/.ipe/ipelets/mouse.lua), change the variable mouse to _G.mouse, and change it as you wish.

If you just want to change a single mouse action, you can instead write:

mouse.middle = "rotate"
