Weechat
Once upon a time there was BitchX. Then there was Irssi. Now there is Weechat. More and more people are switching over to Weechat from Irssi, probably coz the colours make IRC easier to read and follow. Problem is, for the Irssi user, Weechat may be a tad confusing.
Weechat documentation can be tricky to follow, so this page is an attempt to make simple those bizarre and abstract commands.
Like Irssi, you can move between windows/buffers using Alt+<num>. You can also type /buffer <num> (similar to /win <num> in Irssi).
F5 and F6 move to the predecessing and successing buffer, respectively.
You can move buffers (chat windows) with /buffer move. In a channel, type:
/buffer move <num>
(where <num> is any number you want). That channel is now accessible at Alt+<num>.
Special commands
Keybinds
Keybinds are handy, especially if you have over 10 channels open. I use Alt+<num> to get to channels, but clearly this only works from 1 up to 0 (on a keyboard). So for channels in higher numbers, you can bind keys: i.e. Alt+q gets me to channel 11; Alt+y gets me to channel 16.
/key bind meta-q /buffer 11
"Key" and "bind" are self-explanatory. "Meta" is Weechat's word for Alt (so meta-q is the same as Alt+q). /buffer 11 is the command that's executed once meta-q (Alt-q) is typed.
You can build up these to meta-w, meta-e, meta-r for buffer 2, buffer 3, buffer 4, etc etc.
Of course, you can bind any key combo to any weechat command; it's not necessary to make them Alt+<num> commands.
Note: Watch out for caps lock if you're keybinding. If you bind Alt+y to a command, Alt+Y won't work (unless you bind that separately). If you find your binds aren't working, check your caps.
