Drop special handling of ctrl-l in handle_interlink_event.
To make sure that the 'redraw' action works everywhere, first modify
menu_kbd_handler and mainmenu_kbd_handler to handle ACT_MENU_REDRAW; and
second, drop the ACTION_REQUIRE_VIEW_STATE flag from the 'redraw' action in
the 'main' keymap so that it works even if there is no document loaded.
Ctrl-l is already bound to 'redraw' in all keymaps by default, so the
current default behaviour is preserved.
move-link-down-line moves the cursor down to the line with a link.
move-link-up-line moves the cursor up to the line with a link.
move-link-prev-line moves to the previous link horizontally.
move-link-next-line moves to the next link horizontally.
(cherry picked from commit 8259a56e99)
The menu shows a list of all fields of a form, with the possibility to jump
right to that form field when selecting an entry. The menu text is the
basic form field label "Radio button", "Text field", etc. with the form
field name or alt text as the right menu text.
It introduces a new main action called link-form-menu with no default
binding.
Requested by Klaus Knopper, as a mean to improve accessibility for complex,
overloaded pages like ebay.com.
