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\ +"); + +void ShowHelpL() + { + gFed->ShowHelpL(KHelpText().AllocL()); + } +
