Simple Question - Does Hypergraph have feature to assign keyboard shortcuts to run TCL scripts

Hello everyone, I am working on a TCL script for a particular functionality and logic part is working properly. I wanted to know if I can assign a shortcut key to run the script directly instead of doing Run Tcl/Tk Script -> Selecting File. 

As far as I know, hypermesh has this feature but could not find it in Hypergraph. Any help would be appreciated.

Edit: No worries - I am using bind and source commands now so the issue is solved.
Edit: Even though using bind and source helpful, both are them are Tcl/Tk commands so I need this script first to assign shortcuts. So this is good solution but better would be to assign permanent shortcuts, is that possible ?
