Pressing Ctrl+G repeats a command line. You can set up and execute complex sets of editing commands many times.
You can repeat a command a specified number of times b entering the number before the command. For example:
exchanges the next four occurrences of "rename" to "copy".
Use the RP (Repeat) extended command to repeat a command until ED returns an error, such as reaching the end of the file. For example:
moves the cursor to the top of the file, then exchanges all occurrences of "rename" with "copy". The T command (Top of File) changes all occurrences of Rename in the whole file. Otherwise, only the occurrences after the current cursor position are changed.
To execute command groups repeatedly, you can group the commands together in parentheses. You can also nest command groups. For example:
inserts three blank lines (the null string //) after every line containing Workbench.
To interrupt any sequence of extended commands, press any key during execution. If an error occurs, ED abandons the command sequence.
