EventTap seems to be sending the event to the wrong window

[zen0wu]

It's a bit hard to describe, I'll try my best. Not sure if this is the right place to ask, because I don't know if it's a bug or I'm doing anything wrong with my config. So sorry in advance for spamming.

What I did is, I want CapsLock key to be a hybrid Ctrl/Function key on my new keyboard, for example:

• caps+B acts like ctrl+B
• caps+i acts like up arrow
  You get the idea.

My approach is to use an eventTap that's activated when Caps is pressed, and stopped when it's released, the event tap watches keydown event and translate it.

The reason I didn't use modal for it is that,

• modal is not as responsive
• modal doesn't work with long press (repeatfn doesn't really work, for some reason that I'm not sure)

The only problem I've found is, Caps-IJKL now are my arrow keys, if I switch a window using Cmd-Tab, then I press Caps-I, it'll actually trigger a up in the previous window. I have to type something real in the new window to make it switch. Not sure if this is a bug, or it's something I'm doing wrong in the config.

Here's my config: https://gist.github.com/shivawu/a28ab3016956db601df0bba37b75546e

Anyone available to help?

Rather than modify the event you receive in your eventtap callback, try creating a new hs.eventtap.event event and returning that in the table. I'm guessing here, but it's worth a shot.

@cmsj Thanks a lot for the suggestion! Unfortunately it doesn't seem to work

Here's the updated config

local anneEt = hs.eventtap.new({ hs.eventtap.event.types.keyDown }, function(event)
  local kc = event:getKeyCode()
  local mapped = capsMap[inverseKeycodes[kc]]

  if mapped ~= nil then
    key = event:getKeyCode()
    mods = event:getFlags()
    if mapped.key ~= nil then
      key = hs.keycodes.map[mapped.key]
    end
    if mapped.mods ~= nil then
      for _, m in pairs(mapped.mods) do
        mods[m] = true
      end
    end
    return true, {hs.eventtap.event.newKeyEvent(mods, key, true)}
  end

  return false
end)

@shivawu same symptoms as before? :(

[zen0wu]

Yeah... Could you try the same config with "F13" replaced by things like "Caps", should work the same way, right?
