On my Thinkpad T14s Gen 1, the right meta/super/windows key is replaced
|
|
by a "<kbd>PrtSc</kbd>" key. I use <a href="https://swaywm.org/">Sway</a> as my
|
|
Wayland compositor and use the meta keys a lot to navigate and manage
|
|
windows, and having only a left meta key makes some chords difficult to
|
|
use. I thus wanted to remap <kbd>PrtSc</kbd> to Meta.
|
|
</p>
|
|
|
|
<p>
|
|
I found <a href="https://github.com/rvaiya/keyd">keyd</a> which looked
|
|
promising. To use this, I need to know what key <kbd>PrtSc</kbd> maps to in the
|
|
OS. Using <code>evtest</code>:
|
|
</p>
|
|
|
|
<pre><code>Event: time 1674905628.580346, type 4 (EV_MSC), code 4 (MSC_SCAN), value b7
|
|
Event: time 1674905628.580346, type 1 (EV_KEY), code 99 (KEY_SYSRQ), value 1</code></pre>
|
|
|
|
<p>
|
|
It seems like it is interpreted as <kbd>SysRq</kbd>.
|
|
</p>
|
|
|
|
<p>
|
|
To only remap this keyboard and not any other keyboards connected to
|
|
the computer, we'll need the vendor and product id of the built-in
|
|
keyboard. That can be found in <code>/proc/bus/input/devices</code>:
|
|
</p>
|
|
|
|
<pre><code>$ cat /proc/bus/input/devices
|
|
I: Bus=0011 Vendor=0001 Product=0001 Version=ab83
|
|
N: Name="AT Translated Set 2 keyboard"
|
|
...
|
|
</code></pre>
|
|
|
|
<p>
|
|
<code>0001:0001</code>.
|
|
</p>
|
|
|
|
<p>
|
|
Next we'll configure keyd:
|
|
</p>
|
|
|
|
<pre><code>$ cat /etc/keyd/default.conf
|
|
[ids]
|
|
0001:0001
|
|
|
|
[main]
|
|
sysrq = rightmeta
|
|
</code></pre>
|
|
|
|
<p>
|
|
Restart keyd and we're done! The <kbd>PrtSc</kbd> key is interpreted as meta
|
|
instead.
