You can change the case of text by positioning the cursor and pressing Ctrl+F. If the letter is lower case, it becomes upper case and vice versa. Ctrl+F does not change non-alphabetic characters or symbols.
After you press Ctrl+F, the cursor moves to the right. You can hold down Ctrl+F to repeat the command until you change all the letters on the line.
In extended mode, commands are displayed on the command line - or status line - at the bottom of the window. ED does not execute these commands until you press Return or Esc. If you use Esc to execute extended commands, ED remains in extended mode. If you use Return to execute extended commands, ED returns to immediate mode.
Extended commands manage the following:
To enter extended mode, press Esc. An asterisk appears as a prompt in the status line. Extended commands consist of one or two characters. Multiple extended commands can be typed on a single command line by separating them with a semicolon. Commands can be grouped together for ED to repeat automatically. Use Backspace to correct mistakes.
You can also execute commands through the programmable menu and function keys. Reconfigure the menus and functions keys by assigning a command to the key or menu item of you choice as described on page 12-19.
In some cases, commands require arguments, such as a number or a text string. A string argument for an ED command must be enclosed in a pair of identical delimiter characters. In unambiguous situations you can omit the trailing delimiter. Valid delimiters include ", /, \, !, ;, +, -, and %. You cannot use the same delimiter character inside your string. Invalid delimiter characters include letters, numbers, spaces, semicolons, question marks, brackets, and control characters. If a command needs two string arguments, you can enter them together, inserting a third delimiter character. For example, "string1"string2".
You can also ask ED to use a file requester, allowing you to view the contents of the drives and directories in your system.
To invoke a file requester for a load or save command, you must place a question mark (?) before the required string argument. Be sure to include a space before the question mark (for example, sa ?/Text/). Normally, when a command is followed by a string, ED treats the string as the file to be loaded or saved and attempts the operation immediately. However, the question mark indicates that you want to specify the file through a file requester. You must still specify a string after the question mark, but the string becomes the text that appears in the file requester title bar.
