This file was called from the start menu file
at \~PWD~

If you press "e", you will find that you can edit this file
using your default editor as set in the environmental variable,

EDITOR=your_favourite editor

Try pressing "e" now... BUT only if you know how to get out of an editor.
(See below for how to get out of a text editor.)
When you are in the text editor, you will be able to see how the
value of the variable "PWD" has actually been substituted for in
the menu display, ie. \~PWD~

(NOTE: that this is different from the variable substitution when passing
variable values within square bracketed links, ie $variable.) See [sample01]

SETTING VARIABLES WITHIN A DISPLAY

You can also set the value of the variable by \\~hybrowvar=12345678~
Within these quotes is the variable definition  \~hybrowvar=12345678~
which is hidden when the menu file is displayed by HYBROW.

NOTE: If you are looking at this outside HYBROW, you will see that for the
first one, I have inserted another backslash (ie. meaning display the next
character literally) before the first, which disables the variable
definition, and allows HYBROW to display the way in which the command is to
be written. It is the second one that does the variable definition.

In other words, using an "=" equal sign to assign the value and then to display
that value the usual way, ie \~hybrowvar~

This trick is useful if you wish to detect the user's entry to a certain
menu by triggering a variable flag. The variable will not be set unless the
file is displayed by HYBROW. Once the variable is set, it will last for the
whole HYBROW session unless reset.
