Epson 386SX - Manual (Page 196)

For example, you may see this menu:
1 - Run test one time
2
- Run test multiple times
0 - Exit
Suppose the first option is highlighted. If you want to select that
option, just press
Enter (because it is already highlighted). If
you want to select option 2, you can either press 1 or 2; this
causes the cursor block to move to that option. Then press
Enter to select it.
Therefore, when the instructions in this appendix tell you to
select an option, you can either use or to highlight
the option or you can type the number of the option. Then
press Enter. (You must press Enter to start the operation.)
You can press E
SC
any time you want to leave the menu
currently displayed and return to the previous one.
