Buffer clearing and the command separator

! repeats your last command.

\ clears the command buffer and moves on to executing the next one. For example, you can type \recall. The current run path will not be cleared. In some game clients \ is a special character, in which case it must be doubled as \\.

The command separator | lets you enter several commands on one line, or define a multi-command alias. When entering an alias, this symbol must be doubled as ||.
