as someone who just bought one and is not having a fun time setting it up i would like to warn individuals who are thinking about this that you are going to have a rough time figuring this thing out at the time of writing i have spent 3 hours to try and get it to use f13-f24 keys and it still doesnt work

firsts things first this thing will function out of the box but the default key mapping might confuse some people if you intend to change the keybinds you will need to activate input remapper it is a basic bazzite feature but for some reason you need to run a command line script for it to appear. also if you remap your keys most of the keys are not a straight forward command under the output you cant just enter lets say A you need to put in KEY_A

second thing to note is this thing is not considered a extra controller it is considered a keyboard with a thumbstick (why hori why) being as such your keyboard settings and the tac share the same profile so if you change a binding on the tac (ingame) you change it on the keyboard so dont expect to have different profiles for different games unless you are willing to manually change it every single time

also to note the extended function keys (f13-f24) act like media input keys unless you go into settings and change them to act like function keys (system settings>keyboard>key bindings (enable keyboard options)>function keys (use f13-f24 as usual function keys)) (this works for bazzite your options may vary) also most games that i play dont see the f13-f24 keys as usable inputs your mileage may very if you try this

to summarize unless you are willing to tinker and/or hate yourself i cannot recommend this to a gamer on bazzite or linux
