Dash - update Dash keyboard shortcuts so the 'CTRL + TAB' switches between Lenses and 'TAB' by itself moves the focus between categories

Bug Description

Test case:
1. Open the dash
-> "CTRL + TAB" and "CTRL + PAGEDOWN" should switch the user between lenses, in a left to right order
-> "CTRL + SHIFT + TAB" and "CTRL + PAGEUP" should switch the user between lenses, in a right to left order.
-> TAB should jump the keyboard focus between the search result category headers and (if the search filters are open) between the "All" button at the top of each search filter category header.
-> If no item on the dash is currently in focus, pressing TAB should focus the top category header.
-> If a item is already focused, pressing TAB should focus the next category header below.
-> If the item focused is either in the last search result category header, or (if the search filters are open), a button under the last search filter category header, pressing TAB should jump the focus back to the first search result category header.
-> If the search filters are open and the item in the last search result category header is selected, pressing TAB should focus the "All" button to the right of the top search filter category header.

Dash - update Dash keyboard shortcuts so the 'CTRL + TAB' switches between Lenses and 'TAB' by itself moves the focus between categories.

Requested change:
- When the Dash is open, "CTRL + TAB" and "CTRL + PAGEDOWN" should switch the user between lenses, in a left to right order.
- When the Dash is open, "CTRL + SHIFT + TAB" and "CTRL + PAGEUP" should switch the user between lenses, in a right to left order.
- When the Dash is open, TAB should jump the keyboard focus between the search result category headers and (if the search filters are open) between the "All" button at the top of each search filter category header.
- If no item on the dash is currently in focus, pressing TAB should focus the top category header.
- If a item is already focused, pressing TAB should focus the next category header below.
- If the item focused is either in the last search result category header, or (if the search filters are open), a button under the last search filter category header, pressing TAB should jump the focus back to the first search result category header.
- If the search filters are open and the item in the last search result category header is selected, pressing TAB should focus the "All" button to the right of the top search filter category header.

We have an issue that ctrl-pgup/dn is used for switching tabs in some
places, and ctrl-tab in others. We need to resolve that for consistency
across all applications that offer tabs.

In both firefox and chromium (apps most people use lots of tabs in) the use of ctrl-pgup/down is used to move around tabs.

I'd be much happier for us to use those keybindings than ctrl-tab/ctrl-shift-tab (you have to be able to go back too).

Agreed, Tim. But one last thought; what about Super-PgUp/Dn, for
consistency with the "app/window/tab starts with Super" meme?

Super+PgDn can not be pressed with one hand...

As it happens, on my keyboard at least, the Ctrl which is
one-hand-distance from PgUp and PgDn doesn't work in that way. So
switching tabs is a two-hand combo for me currently, I don't know if
that's specific to my keyboard or not.

Mark

Chromium, Firefox & Thunderbird all support both CTRL + TAB as well as CTRL + PAGEUP and PAGEDOWN. I was leaning towards CTRL + TAB because in a unscientific straw poll this seemed to be the most frequently requested option, and also some laptops (e.g. those from Apple) do not have PAGEUP and PAGEDOWN keys. To compare ourselves to the competition, Apple use CTRL + TAB in Safari on OS X, and on Windows both CTRL + TAB and CTRL + PAGEUP and PAGEDOWN are supported.

As long as there is no conflict with other functionality we could support both (in the same manner as Windows), as it is likely that different sets of users will be already used to one or the other of the options, and this is the approach already taken by our main applications.

I've been frustrated a number of times expecting tab completion to work in the search field.

The CUA-inspired scheme we once discussed for GNOME was that there was a sort of hierarchy of modifier key bindings. I forget to what extent we went with it. Here are a few examples:

Session level - Ctrl+Alt+key
Ctrl+Alt+Backspace - kill the X server
Ctrl+Alt+Delete - log out, shutdown, etc., like Windows.
Ctrl+Alt+L - lock screen
Ctrl+Alt+D - show desktop

Window level - Alt+key
Alt+Tab - switch between windows
Alt+F4 - close window
Alt+F9 - minimize window

In-window level - Ctrl+key
Ctrl+Tab - switch between tabs
Ctrl+F4 - close tab or child window
Ctrl+F9 - minimize child window or hide tab

This was before the logo key was ubiquitous and commonly mapped to Super, which would take the place of Ctrl+Alt.

With regards to the comments (#4 & 5) about being able to do the switching with one hand, eg CTRL+PG UP/DN or CTRL+TAB, it appears the latest 12.04 beta updates don't yet include the ability to do this, ie with the right hand CTRL keys.

For Unity2D the changing lens part (Ctrl+Tab, Ctrl+Shift+TAb, etc) has been merged with https://code.launchpad.net/~aacid/unity-2d/addshortcutstochangelens the in-lens Tab navigation is still WIP

Hello John, or anyone else affected,

Accepted unity-2d into precise-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!
