I have just installed Mint 17.1 Cinnamon and I'm finding keyboard shortcuts conflicting with Intellij and Emacs. The one giving me a lot of trouble is the Ins key (lower left of the six keys between the alpha keyboard and the keypad).
When I hit Ins, the display flashes. Using gconf-editor and dconf-editor and the keyboard settings panel, I have been unable to find any binding for Ins. How can I change it?
More generally, is there a text file somewhere storing the keyboard shortcuts? I would prefer to edit that directly than deal with these UIs.
Open Keyboard app and go to Keyboard shortcuts tab. In this place you can change bindings.
