Brick visibility demo - ctrl-arrow up/down

[dylanmc]

The top-left and top-right viewports work as advertised. The bottom one does as expected for left-right movements, but ctrl-up/down arrows affect the top-left viewport instead of the bottom one.

brick version 0.1
vty-5.2.10 (as reported in my cabal sandbox's share/x86_64-osx-ghc-7.10.2 directory)

unsure where the output of cabal freeze goes.

This might be because your terminal emulator isn't sending the same keycodes that Vty expects. Which emulator are you using? (And are you using screen or tmux?)

[jtdaugherty]

(And cabal freeze writes cabal.config.)

I tried this using Terminal.app and I saw the same behavior that you described. I always use iTerm2, though, and it works as expected there.

[jtdaugherty]

It is possible to tell Terminal.app which escape sequences to send for certain keys. You might consider this:

I was able to get this to work by setting sequences for Ctrl-up/down as follows:

• Go to terminal preferences
• Click "Keyboard" for active profile
• Click "+"
• Select "Control" and "Cursor Up"
• For the sequence, click the text box, and press ESC [ 1 ; 5 A
  (Similarly for Ctrl-Down, just B instead of A)

(But for future reference, Terminal.app tends to be more impoverished than iTerm2.)

[jtdaugherty]

Give this a try and if it works, please close this ticket (or let me know what else I need to do).

That workaround (/fix to Terminal) works great. Thanks! (/me shuffles off to download iTerm2)
