The key bindings file can be found from the Settings menu or here:
%appdata%\10x\Settings\KeyMappings.10x_settings
The key bindings file is a regular 10x_settings file.
Keys can be mapped to any 10x command or Python statement
For multi-key bindings separate the keys with a comma. The example below requires the control+S to be presse twice.
Control S, Control S: SaveAll
This will find alt+H to the python HelloWorld function in Example.py. Note that the brackets are not necessary for simple function calls. You can also enter any complex python statement here and it will get evaluated.
Alt H: HelloWorld()
