Regarding cycling channels, I love the use of CTRL[+SHIFT]+TAB, although it seems impossible to get to query or custom windows using this method. I kind of remember using CTRL+N to cycle channels but I would rather it not, as using tab and shift tab is more common and better for cycling (afaik it never used to work well and there wasn't a backwards cycle?)
Ditto... CTRL[+SHIFT]+TAB to cycle thru every window is the obvious choice. I mean people don't want to remember that CNTRL-Q cycles just query windows in just mIRC... and CNTRL-N for channels, etc. Stick to the common interface guidelines...
For people who actually want to cycle using CNTRL-N/CNTRL-Q/ETC... include an option for legacy cycle shortcut keys.
