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\

========\n\

^L, F1  Get help\n\

^N      New document\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\

^F      Find text\n\

^K      Delete current line\n\

^G      Go to line\n\

^R, F5  Redraw the screen\n\

^X      Cut (see below)\n\

^C      Copy (see below)\n\

^V      Paste\n\

\n\

^P, F2  Switch to Previous view\n\

^], F3  Switch to Next view\n\

^W, Esc Close current doc\n\

^Q      Quit and close all docs\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\
