If you were wanting to change your key bindings to alter your Normal Attack, Skill, and Burst key bindings, then Honkai: Star Rail would politely like to say, ‘No, heck off.’
Can you Change In-Battle Key Bindings?
In Honkai: Star Rail’s settings menu, there is an odd option under Key Bindings. It blew me away at first, but I found out there is an option that isn’t there. When summoning your mouse to the screen, you can change the Key Binding. Using this, you can click on all kinds of icons on the screen, including the Cellphone (Your Menu), Tutorial, and Quests on top left and the Hot Bar Icons on top right.
After that is out-of-battle keys. This involves all of the usual buttons such as WASD, inventory, switching characters–the whole shenanigans. But uh, Hoyoverse. Kindly. What the hell?
How to Change Key Binds in Honkai: Star Rail
The key bindings in Honkai: Star Rail can still be changed as long as they are not corrected during battle. Your F-keys are assigned to the Hot Bar events that you see at the top right of the screen, so you can change the movements of the characters. The Events Tab, Battle Pass, Warp, and Interastral Peace Guide can all be accessed with certain F-Keys.
