Sory for the late reply, i was busy lately. You are able to see the TTB function name in CIW. To make it visible to user, at CIW, go to Options->Log Filter and check the option for "Accelerated input ( menu and bindkeys commands, form and field value setting and callbacks, etc)".
After the option is checked, any function that you use in cellview will be display in CIW. For example, turbo ruler. The command show in CIW is _leTbCommand("_leTbRuler(nil nil t)" t). You can set the bindkeys as below:
hiSetBindKey("Layout" "<Key>k" "_leTbCommand(\"_leTbRuler(nil nil t)\" t). ")
** Please bear in mind that the TTB function only applicable when TTB is activated.
