Prevent thread expansion with j/k navigation keys

[labrnth]

Good morning,

I'm wondering if there is a way to prevent email threads from expanding when using j/k navigation keys. I'd like to be able to map h/l keys to expand and collapse threads like (like using Vim). With that said I'm very grateful for this add-on.

Cheers,
-Chris

Use the unset binding to unbind built-in key bindings.

Command syntax

Do you want the command for the "Ignore Thread" menu item?

i.e. Menu Bar > Message > Ignore Thread

Toggle "Ignore Thread" menu item:

window.goDoCommand('cmd_killThread');

Check "Ignore Thread" menu item:

if (!window.gFolderDisplay.selectedMessageThreadIgnored) window.goDoCommand('cmd_killThread');

Uncheck "Ignore Thread" menu item:

if (window.gFolderDisplay.selectedMessageThreadIgnored) window.goDoCommand('cmd_killThread');

@morat523035 thanks for you response. I'd like to be able to continue suing J and K to navigate up and down the message list but when I come to a thread (thats collapsed) I dont want the thread to expand as I go up/down the list. I would like to use the keys H and L to expand or collapse the thread when needed. If that makes sense.

Kind of how the arrow keys currently function. I literally would like to bind J and K to the up/down arrow keys and H and L to the left/right arrow keys. Is that possible?

You want to synthesize a keypress event on the active window. The nsIDOMWindowUtils.sendKeyEvent method doesn't work anymore. Try the nsIDOMWindowUtils.sendNativeKeyEvent method.

(function () {
  var KEYBOARD_LAYOUT_EN_US = {name: 'US', Mac: 0, Win: 0x00000409, hasAltGrOnWin: false};
  var WIN_VK_DOWN = 0xe0500028;
  window.windowUtils.sendNativeKeyEvent(KEYBOARD_LAYOUT_EN_US, WIN_VK_DOWN, 0, '', '');
})();

Thanks a ton for this helpful comment. Here is the full set of hjkl mappings in case anyone else needs to do this:

"h": "(function () {var KEYBOARD_LAYOUT_EN_US = {name: 'US', Mac: 0, Win: 0x00000409, hasAltGrOnWin: false}; var WIN_VK_LEFT = 0xe04b0025; window.windowUtils.sendNativeKeyEvent(KEYBOARD_LAYOUT_EN_US, WIN_VK_LEFT, 0, '', '');})();",
"j": "(function () {var KEYBOARD_LAYOUT_EN_US = {name: 'US', Mac: 0, Win: 0x00000409, hasAltGrOnWin: false}; var WIN_VK_DOWN = 0xe0500028; window.windowUtils.sendNativeKeyEvent(KEYBOARD_LAYOUT_EN_US, WIN_VK_DOWN, 0, '', '');})();",
"k": "(function () {var KEYBOARD_LAYOUT_EN_US = {name: 'US', Mac: 0, Win: 0x00000409, hasAltGrOnWin: false}; var WIN_VK_UP = 0xe0480026; window.windowUtils.sendNativeKeyEvent(KEYBOARD_LAYOUT_EN_US, WIN_VK_UP, 0, '', '');})();",
"l": "(function () {var KEYBOARD_LAYOUT_EN_US = {name: 'US', Mac: 0, Win: 0x00000409, hasAltGrOnWin: false}; var WIN_VK_RIGHT = 0xe04d0027; window.windowUtils.sendNativeKeyEvent(KEYBOARD_LAYOUT_EN_US, WIN_VK_RIGHT, 0, '', '');})();",
