How to set control_L+hjkl to Left/Down/Up/Right?

[withshe]

I can not write a json config file by myself, please give me a sample, Thanks!

You will have to wait till #16 is fixed.

@withshe, I've hard coded the arrows as fn+hjkl here: watsoncj@5531032

@watsoncj, if I wanted to change your setup to l_cntrl+hjkl, how would I do that? I tried going from source but I couldn't get a successful 'MAKE' command to run. Any suggestions?

@chinchin96 Complex modifications are supported in latest beta (since 0.91.3 or so). Here is example of karabiner.json for fn+hjki

@MyDogTom, you're the man! Thank you for this. Was able to get everything remapped for ^hjkl.

Do you happen to know if the functionality for replicated scrolling with D/D+S/D+S+F + HJKL is available? I wasn't able to find documentation around this (or your mapping file that you provided). I know things are still a work in progress so let me know if that's the case.

Thanks again!1

[itainoam]

@chinchin96, how does the scrolling work with this keybinding? Just curious :)

@MyDogTom, any way to set key repeat for the hjkl binding? So holding hyper+hjkl will send repeating arrow commands.

[MyDogTom]

@chinchin96 Sorry, I don't know. You can check https://github.com/tekezo/Karabiner-Elements/tree/master/examples for more "inspiration".

@itainoam Repeated commands while holding initial combination works perfectly for me. I'm mapping caps_lock -> fn and caps_lock + ijkl to navigation with arrows. Here is my complete karabiner.json

Thanks @MyDogTom!

[lyleinnes]

another big thanks to @MyDogTom !

I've copied the example you posted above and swapped out the fn for left_control.

this gives me the layout i'm used to with my pok3r mech keyboard which is a great relief.

because I'm new to this (and OSX), i must ask, will i miss out on any default left_control functionality by assigning these properties?

I'll include my karabiner.json file for reference.
