If you want to run a Python script in Poser using an assigned keyboard shortcut, you can.
1. The script must be in the software’s ScriptsMenu folder or sub-folders…
C:\Program Files\Poser Software\Poser 12\Runtime\Python\poserScripts\ScriptsMenu
2. Rename your target script filename in the following format…
my_fabulous_script###Alt+C.py
Use of Ctrl or Shift and Alt are permitted, as are capital letters. Capital letters correspond to a lowercase key-press: e.g. C = c.
3. Close and reload Poser. Try your new keyboard command to invoke the script. Tested and working on Poser 12, and once done you see the shortcut on the drop-down if you look there…
With this in place you can now also use mouse-gestures, tied to a keyboard shortcut… which in turn invokes the script.
