- /* EEL code file for editing the Interrupt List */
- /* */
- /* Written by Ralf Brown */
- /* LastEdit: 12 Jan 97 */
- /* */
- /* This EEL file adds the following keybindings: */
- /* Shf-Alt-A add an Access: section to the current entry */
- /* Shf-Alt-B add another BUG: to the current entry */
- /* Shf-Alt-D add a Desc: section to the current entry */
- /* Sft-Alt-I add an InstallCheck: section to current entry */
- /* Shf-Alt-R add a Range: section to the current entry */
- /* Shf-Alt-S add a Size: section to the current entry */
- /* Alt-I add an Index: section to the current entry */
- /* add another Index: line if already on Index: */
- /* Alt-N add a new note to current entry or data struct */
- /* Alt-P add a Program: section to the current entry */
- /* Alt-R insert Return: at start of line */
- /* Alt-S insert SeeAlso: at start of line */
- /* F11 insert a blank separator line */
- /* ^F11 create Format of: header */
- /* Shf-F11 create Values for: header */
- /* Alt-F11 create Call with: header */
- /* Alt-F12 create Bitfield for: header */
- /* F12 add the interrupt number to the separator line */
- /* preceding the current entry */
- /* ^F12 jump to a specified entry */
- /* */
- /* It adds the following unbound commands: */
- /* renumber-tables */
- /* make-distribution */
- /* */
- /* Other: */
- /* adds intlist-mode for .LST and .1ST files */
- /* switches current buffer into intlist-mode on loading */
- /* maintains a table counter which is inserted each time */
- /* a table is created in the text */
- /* performs syntax highlighting (Epsilon v7+) */
