It’s been a while, and much has happened. I stumbled upon many great things that redefine the way I interact with macOS as a power user. Especially relevant to my past posts though, are neovim with dein, a refined iTerm 2 (previously I used a patched version to achieve a borderless version with increased padding), khd and kwm, and finally Übersicht (which is German, and translates to overview).
This post however, is solely dedicated to
kwm is a tiling
window manager, and
khd is a hotkey manager, to which I’ll come in a second.
Tiling window management is a totally different concept to what we normally do
on macOS. We click on windows and drag them around, order them like we want, and
completely rely on the mouse for interactions (except for
cmd + TAB that is).
As we all know, using the mouse is inefficient. Especially when it comes to
ordering windows. That’s why windows started to come with hot corners, which
allow you to drag a window to the very right of the screen to have it occupy the
right half of your screen. You drag it to the center top to let the dragged
window occupy the screen completely. You geht the idea. Similar tools have been
around on macOS for a long time. I started using Moon and others, and lately
found Magnet. These tools are normally
quite limited in their capabilities and response time with such tools is never
kwm therefore is kind of a supercharged snapping tool. You can think of
a program running on your mac that waits for commands that you can give with
kwmc, or, well,
is a tool made from the developer of
kwm that allows the binding of these
commands to actual hotkeys.
khd seems to have two modes, the prefix mode, and
the … modes mode I guess (see here).
The modes mode seems to behave like
vim, which I like. The prefix mode reminds me of
emacs. So for both religions you have a compatible mode of operation. How awesome is that?
In order to start using
kwm simply install them with
brew install koekeishiya/formulae/kwm
brew install koekeishiya/formulae/khd
To get started we’ll use the default configurations for both:
cp /usr/local/opt/khd/khdrc ~/.khdrc mkdir -p ~/.kwm cp /usr/local/opt/kwm/kwmrc ~/.kwm/kwmrc
kwmrc configures things like the border color for focused windows,
the blacklisting of apps that shouldn’t be tiled but floated instead.
The comments in the config file will help you a lot with getting started.
I am currently using an unchanged version of it, but will personalize it in the future.
As for the
khd config, this is where the magic happens. Here it is defined how you interact with
The default runs
khd in the prefix mode, which I think of as
emacs mode. You enter the prefix,
which by the default configuration is
ctrl + s, and you then enter what you want
khd to do, quickly.
At least for all the hotkeys listed with
prefix +. There are some that use
ctrl + alt + something
or such, which can be used just like any hotkey, you press them all at once.
So now you have
khd running. After you finally found out how to use the prefix mode, you can
start getting faster with organizing your windows properly without any mouse movement involved.
If you don’t use fish that is. If you do, read on.
How does this work anyway?
After I set it all up, I was lost. I had a terminal open with the
to help me navigate this new land of awesomeness. But I couldn’t really use the
prefix stuff and the responsiveness of this setup was overall disappointing.
After some googling around, I found this issue
though. It seemed that fish does, what fish always seems to do, it breaks things, because no
one takes care of fish compatibility. TL;DR: you have to edit the launch agent, the little helper
thingy that keeps care of opening apps when you log in.
The important part are the lines
The file can be found under
~/Library/LaunchAgents/homebrew.mxcl.kwm.plist. After making the changes
log out and in again. You now should have a snappy
kwm. How cool is that? You can finally
prefix hotkeys and your commands get executed in an acceptable response time.
And now what?
I haven’t had the time to fiddle around with this setup much. I’m quite busy
right now, so I stick with the default config for now. I probably will check out
modes mode. But for now this setup improves the way I did things before
The features I like the most are:
- mouse focus follow: the window where the mouse is over gets the focuse. I loved this about pekwm back in my linux days.
- give focus to screen: with one hotkey you can move your mouse to the center of a screen. For someone with a dual monitor setup this is saving a lot of mouse movement!
- automatic tiling of windows
- send windows to spaces, screens and positions on the screen
If these sound like something that your work can benefit from, then I definitely recommend
kwm enough. If it seems to much to configure and something bugs you about it,
you could also have a look at Amethyst,
another tiling manager for macOS.
As for the rest that I mentioned, that will hopefully be another post.
I have to update my
dotfiles on github anyway. But before I can do that, I have
to fix some issues with my new desired color scheme for
fish. So stay tuned for more!
