Zoom window
The window is zoomed out to the screen-size. Press Zoom window again to return to original size.
Previous line
When the editor prompts for a string (as in Search), pressing Previous line causes the most recently entered string to be shown.
File mask
Press this command when the filename browser in the file-name input box is active. You can then enter the file-mask (e.g. *.sm).
Terminate input
The key to use to terminate user input.
modes: Insert and Overwrite. In Insert mode, anything you type is inserted at the cursor position. In Overwrite mode, pressing a key replaces the current character at the cursor position with the new typed character. Initially, the editor operates in Insert mode, to switch modes, press the <Insert> key or <Ctrl>V. (<Ctrl>V means to hold down the <Ctrl> key on your keyboard while you press V. The V need not be in upper case.)
Unlike a more standard word processing program, the editor does not have word-wrap. You must press <Enter> at the end of each line.
The editor has an auto indent feature that allows subsequent lines to automatically indent. If you leave several spaces at the start of a line, use
<Ctrl>OI to indent subsequent lines the same amount. The command sequence is a toggle, so you need only press <Ctrl>OI again to stop indenting.
Sometimes you may want to see more than the area covered by the current window. You can zoom the window, expanding it to the size of the entire screen, by pressing <F5>. To return the window to its usual size, press <F5> again. For other window commands, such as moving and resizing a window, see the window command table, below.
The editor uses approximately 70 commands, which can be grouped into 6 main categories:
1. cursor movement commands 2. insert and delete commands 3. search and replace commands 4. file commands
5. block commands
6. miscellaneous commands
