Thanks for your analysis. The layout is like this: 1. It always has two panes, left and right; 2. Suppose we have windows A, B, C, D and E; currently left pane displays A and right pane displays B; A is focused: (A)|B [C, D, E] window in () is focused, windows in [] are not visible; 3. When pressing M-J/K, left pane switches between all windows expect B, focus in always on left pane. so it can become: (C)|B [A, D, E] (D)|B [A, C, E] (E)|B [A, C, D] 4. When pressing M-S, focus switches between left and right pane. so it can become: A|(B) [C, D, E] 5. When focus is on right pane, when pressing M-J/K, right pane switches between all windows expect A: A|(C) [B, D, E] A|(D) [A, C, E] A|(E) [A, C, D] Is there any solution for this requirement? lars On Sat, 20 Mar 2010, Adam Vogt wrote:

Hi All,
I like the TwoPane layout, but need to special configuration:
Suppose we have windows A, B and C. Now A is on left pane and focused, B is on right pane, C is not visible: (A) | B, C
Now I need a special HotKey, when triggered, it keeps B untouched, just switch between A and C on the left pane.
And I also want another HotKey to switch between left and right pane.
Is that doable?
I need it a lot, thanks very much.
best lars
These can all be accomplished by manipulating the ordering in the StackSet.
You'll have to decide what is to happen with more windows, when:
(A) | B, C, D
So does it mean going through these steps:
A | (D), B, C -- insert D above B, swapping the order of B C to C B -- is also possible, but not done here.
promoteLast :: W.Stack a -> W.Stack a promoteLast (W.integrate -> a:(reverse -> l:ls)) = maybe undefined W.focusDown (W.differentiate (a:l:reverse ls)) promoteLast a = a
promoteLast' probably doesn't deserve a name, but it should be enough of a hint for adding keybindings.
promoteLast' :: X () promoteLast' = windows (W.modify' promoteLast)
Then to go back put the second window from the top at the end:
A | (D), B, C (A) | B, C, D
toEnd :: W.Stack a -> W.Stack a toEnd (W.integrate -> a:d:rest) = fromJust (W.differentiate (a:rest ++ [d])) toEnd a = a
toEnd' :: X () toEnd' = windows (W.modify' toEnd)
I'm not sure what you want by switching between the left and right panes, in that what's supposed to happen when you start here:
A | B (C) D
Then 'switch' to the A, then press M-j, then M-k. Do you end up back at A, was the intermediate B or was it C?
Depending on how you answer (I can't think of any reason to choose one option over the other), you may have to store some additional state, either as a layout that calls TwoPane, or as some code that calls some state defined in XMonad.Util.ExtensibleState (not released yet).
