Has anybody found out how to set shortcut keys for those frame range menu items? Would be efficient to switch back and forth between FullLength and Cut Length with the press of a button.
And I get it can be done via customizing the code but maybe one of you has already found out the exact spot in the source code for it 
Thanks,
Patrick

After further investigation, I found that it is possible to add hotkeys by modifying ./Plugins/Mu/shotgrid_mode.mu file.
Please try adding the following code around line 2464 to this file and check if the hotkey is applied as expected:
app_utils.bind("key-down--<key>", changeEdit("all", Prefs.PrefLoadRangeFull,), "Load Range Full");
app_utils.bind("key-down--<key>", changeEdit("all", Prefs.PrefLoadRangeCut,), "Load Range Cut");
