I have just started with developing GUI extensions in Tridion 2013 SP1. I am facing difficulties in getting it set up correctly first.
I have searched and found few examples on tridion stackexchange which helped me setting up editor.config, command file(.js), styling for the extensions.
Particularly, below answer mentions something like "Correct Frame" to be chosen first: GUI Extensions | Editor extensions improvement
My question - What is a frame here and how to choose the correct frame so that the aliases like: $commands, $cme are recognized?
