I know that you can do ⌘+1, ⌘+2, etc to switch between channel 1, channel 2, etc of a particular server that you are currently on. If you have multiple servers that you are connected to, is there any shortcut to switch between the servers?
You can use the keyboard shortcut Command+Control+1...0 to switch between servers while using Limechat.
Example: Use Command+Control+5 to switch to server 5.
