1326746 - Can't access text selection in last selected iframe via keyboard: Shift+F6 doesn't switch to the last frame

Status: NEW

(Firefox :: Keyboard Navigation, enhancement)

Description

[arni2033]

>>>   My Info:   Win7_64, Nightly 49, 32bit, ID 20160526082509
STR_1:
1. Open url [1]
2. Select text "regression "
3. Click in urlbar
4. Press (Shift+)F6

AR:  The page is focused. Iframe is blurred (not focused). Selected text is unavailable for copy
ER:  Either X or Y
 X) Step 4 - selected text should be blue (F6 should put focus to where it was)
 Y) There should be another way to quickly make last selected iframe focused,
    and selected text in that iframe - available for copy

> [1] data:text/html,world<iframe src="data:text/html,Firefox regressions since version<button>28">

STR_2:
1. Open url [1]
2. Focus button "28" on the page
3. Click in urlbar
4. Press (Shift+)F6

AR:  The page is focused. Iframe is blurred. The button is unavailable for Enter/Spacebar key
ER:  Either X or Y
 X) Step 4 - the button should be focused (F6 should put focus to where it was)
 Y) There should be another way to quickly make last selected iframe focused,
    and focused element in that iframe available for keyboard interaction

Note:  What expected in this bug is
1) This support page (http://mzl.la/16NAhwz) says that (Shift+)F6 is "Move to Previous/Next Frame",
   which is clearly a lie (see STR_1, STR_2). It doesn't switch to <iframe> frame.
   If F6 isn't supposed to switch to next frame, the page should accurately describe what F6 does.
2) Some way to quickly put selection where it was before I focused urlbar:
2.1) It's best to have a shortcut to put focus to where it was on the page before user focused urlbar.
2.2) If F6 isn't supposed to do that, (2) implies Ctrl+(Shift+)F6 or some other shortcut for that.
2.3) If there's no plans to assign a shortcut for that, then (2) implies that
     there should be a shortcut to cycle throught frames list.
2.4) If F6 isn't supposed to do that, (2) implies Ctrl+(Shift+)F6 or some other shortcut for that.

Mass bug change to replace various 'parity' whiteboard flags with the new canonical keywords. (See bug 1443764 comment 13.)
