Fed Help\n\+
−
========\n\+
−
Fed is a basic console text editor. Its interface is similar to pico/nano. It can handle ASCII, UTF-8 and UTF-16 format files, different line endings, very large files, copy and paste, and opening multiple files at once.\n\+
−
\n\+
−
The supported commands are given below. The control key is represented as a caret '^', so ^G means Control-G.\n\+
−
\n\+
−
Commands\n\+

^O      Open document\n\+
−
^S      Save document\n\+
−
^A      Save as\n\+
−
\n\+
−
^U      Page up (alternative to PgUp key)\n\+
−
^D      Page down (alternative to PgDn key)\n\+
−
^T      Go to top of document\n\+
−
^B      Go to bottom of document\n\+
−
\n\+
−

Press ^W to close this window, or use ^P etc to cycle between the help and other documents.\n\+
−
\n\+
−
Clipboard support\n\+
−
=================\n\+
−
The standard Symbian clipboard is supported. You can use ^V to paste into the frontmost document. Cut and copy are two-stage operations, because of the limitations of the console:\n\+
−
\n\+
−
To begin a cut/copy operation, press ^X or ^C. Then move the cursor to the other end of the selection you want to make, and press ^X/^C again to confirm the cut/copy operation.\n\+
