Keyboard commands, which we shall consider to include mouse commands, are referred to in documentation in such a way as to suggest the actual characters with modifiers that you enter to invoke them. Examples are

`all' `>' `=' `{(DOWN)(c-u)(c-j)}'
`(mouseleft)' `(c-(mouseleft))' `(m-(mouseleft))' `(m-(mousemiddle))'
`(cm-(mouseright))'

The shift, control, and meta modifiers are indicated by c,s, and m, and synonymy of character sequences is indicated by {<words><words>}.
Other special characters may be found in the edit menu SpecialChars.

Invoking Commands.

To invoke a command, enter the sequence of characters indicated in the nomenclature for the command. An identifier or numeric string that is not bound to a keyboard command is interpreted as inserting the identifier or numeric string in a way determined by the editing context (see EditContext). To avoid amiguity, commands that end with an identifer or digit must either be terminated with ` ' or immediately followed by a command starting with a non-identifer character.
Here are the characters considered identifier characters:
`abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789 ''

Commands starting with ordinary printing characters cannot be issued when the Nuprl cursor is located inside text, since ordinary characters in text are taken as self-inserting. Nor can (rubout) used inside text except to delete the character in front of the cursor.

`(c-g)' clears the command scanning buffer so that command entry can be aborted. Unfortunately, clicking the mouse in another window also clears the buffer of everything preceding the mouse command.

Changing keyboard commands.

Keyboard commands have an internal name and an external binding which is displayed in the notation referring to the command. doc for edit cmd review2 for how to change keyboard command bindings.
