When the cursor is at a location corresponding to some types of argument (such as an ID), a list of applicable values appears above the text box. Pressing Tab ↹ while entering commands cycles through possible commands or arguments, and can be used to auto-enter the coordinates of the block looked at before entering the chat. The ↑ and ↓ keys can be used to view previously entered text, including all previously executed commands. Using the / key also enters the forward-slash that commands require as a prefix, so it is a useful shortcut.
In the client, commands are entered via the chat window, which is displayed by pressing the T / / , or, / key.
