This sub-menu includes a number of recently opened files or projects
or mathematical operation for your maximum convenience.
If the user needs to reopen a file which has just been in use a short
time ago, he can select this file directly from the recent files sub-menu
without time consuming navigation to its original location. The same applies
to projects and mathematical functions.
The list of recently used files, projects or mathematical functions
will be updated automatically. Older items will be removed after a certain
time automatically. The number of recognized files, projects or mathematical
functions can be configured in the Options dialog.
