Rename Clip Dialog
Advanced > Miscellaneous Functions > Rename Clip Dialog
Press Ctrl+R on any clip to bring up the Rename Clip dialog box.
Here you can assign a better title to the clip, and you can also change or set a "shortcut".
For more information, see ShortCuts.
The Title limit is 60 characters, and the Shortcut is 64 characters.
TIP: If you have a series of shortcuts to enter, be sure to enable the "Carry-Over Last Prefix option. This will cause each clip to remember the "prefix" (all text up to the last ".") from the previous clip.
