I reply your post about Mouse gestures
But i think that you are using CCF ME version now.
(This is a CCF ME command: "CTRL L =luamacro(quickgroupmenu)
This command show Group menu, i think. If you don't use Groups you not need it.
In K-Meleon we use the F6 key to select URL bar. You can use the ID command ID_SELECT_URL to do it with other keys like: CTRL A = ID_SELECT_URL
I also checked out the documentation on gestures. Like I said, you can change the rocker gestures using the config file (no gui access) but I could not find support for scroll wheel gestures.
CCF ME versions have a GUI to preferences, click in Preference toolbar button.
You can found a "Gestures" tab to setting Gestures, but scroll wheel not is implemented in GUI yet (I have last stable version available 0.085)
But you can found in \defaults\prefs\kmeleon.js file next preferences about Mouse wheel:
# Mouse wheel with control key: Zoom
# Mouse wheel with shift key: big scroll
A mouse gesture is defined by default, with Right click and Scroll wheel Up go to top of page and with Scroll Down go to bottom of page.
