It would be nice to see what actual commands input are actually performed when using any of the Invision's GUI-triggered features (ie from contextual menu)
The verbosed input commands could get displayed in an isolated tab or window
some exemple from feature within <channel>'s context menu):
Ex1. NickServ's Access List
From GUI (Invision's Context Menu): ---- Services ------ > Nickserv > Access > List
From CLI (cmd input): > /msg Nickserv Access list
Ex2: System Info
From GUI (Invision's Context Menu): Display in Channel > System info
From CLI (cmd input) > ??????
