User menu is the most interesting innovation of mcedit. To make it functional mcedit author (Paul Sheer, who is also the author of GUI version of editor called cedit) provided a couple very interesting and useful macrovariables. One if %b, the other is %c.

Here is default mcedit menu (for historical reasons stored in the file cedit.menu):

shell_patterns=0    # expression type

# The macros are:
#
# %c The cursor column position number. For edit menu only.
# %i The indent of blank space, equal the cursor column 
#    position. For edit menu only.
# %y The syntax type of current file. For edit menu only.
# %b The block file name.
# %f The current file name.
# %n Only the current file name without extension.
# %x The extension of current file name.
# %d The current directory name.
# %F The current file in the unselected panel.
# %D The directory name of the unselected panel.
# %t The currently tagged files.
# %T The tagged files in the unselected panel.
# %u and %U Similar to the %t and %T macros, but in
#    addition the files are untagged. You can use this macro
#    only once per menu file entry or extension file entry,
#    because next time there will be no tagged files.
# %s and %S The selected files: The tagged files if
#    there are any. Otherwise the current file.
# 
# %% The % character
#
# %{some text} Prompt for the substitution. An input box
#    is shown and the text inside the braces is used as a
#    prompt. The macro is substituted by the text typed by the
#    user. The user can press ESC or F10 to cancel. This macro
#    doesn't work on the command line yet.
