How to turn caps lock + W/S/A/D into Arrow Keys

[weiweihuanghuang]

Hi, thanks again for maintaining this app!

I tried the following, but what happens is that it works but I can't hold down caps lock and w and make it persist as up arrow, it works once then goes back to w.

Here is the EventViewer

Any possibility here?

@weiweihuanghuang I've run into the same problem: when used as a mandatory modifier, caps_lock is not being removed from the to event definition, creating problem when keeping it pressed down for multiple command sequences.

I've been able to work around this problem by using a "virtual modifier" as described in https://pqrs.org/osx/karabiner/json.html#virtual-modifier.

Just for reference, this is my commit that fixed my definitions for ⇪+0 to ⇪+9
