| + | * Commands are executed by following them with the key sequence **Esc Esc** instead of **Enter**. An arbitrarily long sequence of commands can be entered and executed together. | ||

| + | * TECO considers files containing form-feed characters (ASCII 0x0b, **^L**) to be composed of multiple pages with each page consisting of the text between form-feed characters or the beginning or end of the file. TECO will only read into the buffer and edit one page at a time. To edit a multi-page file, complete editing on the first page then use the **P** command to save the page to the output file, reinitialize the buffer, and read the next page from the input file. Once a page has been saved with the **P** command, it may not be revisited except by saving the entire file and restarting the editing process from the beginning. Repeat the process until all necessary pages have been edited. The **EX** command automatically copies any unedited pages in the input file to the output file before exiting. | ||
