Pull-down and cursor menu labels use special characters (such as ->, <-, and <-<-...) to control the hierarchy of cascading menus. These special characters indicate submenus and last items in submenus, and can also terminate all parent menus. Each special character string must come first in an item label.
The special character -> indicates that this item has a submenu, as in the following example:
[->UCS]
If you pull down the View menu and choose the Display item or move the cursor to the right end of the item, the Display submenu is displayed.
The special character <- indicates that this item is the last item in a submenu, as in the following example:
[<-&Z Axis Rotate]^C^C_ucs_z
Special characters <-<-... indicate that this item is the last item of a submenu and also of its parent menu.
