113 Fed Help\n\ |
|
114 ========\n\ |
|
115 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\ |
|
116 \n\ |
|
117 The supported commands are given below. The control key is represented as a caret '^', so ^G means Control-G.\n\ |
|
118 \n\ |
|
119 Commands\n\ |
|
120 ========\n\ |
|
121 ^L, F1 Get help\n\ |
|
122 ^N New document\n\ |
|
123 ^O Open document\n\ |
|
124 ^S Save document\n\ |
|
125 ^A Save as\n\ |
|
126 \n\ |
|
127 ^U Page up (alternative to PgUp key)\n\ |
|
128 ^D Page down (alternative to PgDn key)\n\ |
|
129 ^T Go to top of document\n\ |
|
130 ^B Go to bottom of document\n\ |
|
131 \n\ |
|
132 ^F Find text\n\ |
|
133 ^K Delete current line\n\ |
|
134 ^G Go to line\n\ |
|
135 ^R, F5 Redraw the screen\n\ |
|
136 ^X Cut (see below)\n\ |
|
137 ^C Copy (see below)\n\ |
|
138 ^V Paste\n\ |
|
139 \n\ |
|
140 ^P, F2 Switch to Previous view\n\ |
|
141 ^], F3 Switch to Next view\n\ |
|
142 ^W, Esc Close current doc\n\ |
|
143 ^Q Quit and close all docs\n\ |
|
144 \n\ |
|
145 Press ^W to close this window, or use ^P etc to cycle between the help and other documents.\n\ |
|
146 \n\ |
|
147 Clipboard support\n\ |
|
148 =================\n\ |
|
149 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\ |
|
150 \n\ |
|
151 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\ |
