The @onscreen{Add User-defined Keybindings...} menu item in the
@onscreen{Keybindings} sub-menu of @onscreen{Edit} selects a file
containing Scheme definitions of keybindings. The file must contain a
single module that uses a special keybindings language,
@scheme[framework/keybinding-lang]. For example, a file named
@filepath{mykeys.ss} for keybindings might contain the following
code:

Note that @schememodname[drscheme/tool-lib] adds all of the names

your keybindings module, which helps in defining DrScheme-specific
keybindings.
For example, this remaps the key combination ``control-a'' key to ``!''.
