There are several commands in MicroEMACS that can be used to examine or change key bindings. These commands are not normally bound to a particular key. As with any unbound commands (also called "extended" commands), they can be used by entering M-X (ESC X), then typing the command name in response to the prompt : on the echo line.

[unbound] (display-bindings)

This command creates a pop-up window that contains a table of the current keyboard bindings. Each entry in the table contains the key name, and the name of the command that the key invokes. You can save this table to a file by using C-X N to switch to the window displaying the table, then using C-X C-W to write the table to a file.

[unbound] (bind-to-key)

This command prompts the user with Function: for a command name, then prompts with Key: for a key (or key combination). The command is then bound to that key, so that all subsequent uses of that key cause the associated command to be executed. The command name can be any of those listed by the display-bindings command, or any of the commands described in this section.

[unbound] (help)

This command waits for the user to enter a key, then displays on the echo line the command name that is bound to that key. On PCs, this function is bound to F1.
