An Edit-Window contains a complete editable (ASCII) file or - in case of a PHP-file -
either the main-part or one of the functions. Editing a PHP-file may thus result in
serveral open Edit-Windows at the same time.
When requesting an upload (via context-menu or by pressing <CTRL>U) all Edit-Windows
pertaining to a file are collected and the file is saved and sent to the remote site.
The windows remain open.
Each Edit-Window has a status-line at the top. Its color is red except for PHP-functions,
which are yellow).
You may at any time invoke the Context-Menu over the Edit-Window, where lots of auxiliary
functions are at your disposal. They should all be self-explanatory.
