Can't rebind keys to backspace.

As stated in the title, it doesn't seem that you can use backspace as a bindable key. When you select a key to rebind, the UI says to "press escape to exit" but backspace also does this. This doesn't seem intended as in PoE 1 you can use backspace as a bindable key.

I use a glove 80 split keyboard and would like to use backspace as its more intuitive than space.

Edit: Tried to manually edit the config.ini file by adding the backspace keycode (8) to the field I want but when I load up the client, it doesn't show any key being bound (the field is just blank), though it also doesn't tell me that its unbound. I obviously can't test if this works in game until tomorrow.

I too am having this issue. I use a split ortho keyboard (Advantage 360) and cannot rebind using backspace.

I specifically am trying to rebind the keys that are normally "space" to "backspace" and cannot seem to do it. Dodge roll was the main key, but also the skip button.

Similar to the OP, I tried editing the config manually, but it did not seem to work as I expected.

I also have the Advantage 360 and had the same issue with PoE 1.

The solution is to manually edit the key bindings. For this you have to close the game.

Then open explorer and navigate to the game folder in your home directory.

It is under

"

Documents/My Games/Path of Exile 2

and then edit the file

"

poe2_production_Config.ini

.
Or just copy this into the notepad open file dialog:

"

%USERPROFILE%/Documents/My Games/Path of Exile 2/poe2_production_Config.ini

Find the key that you want to change and set it to "8", which is the key identifier for backspace.

For example I changed my dodge roll like this

"

use_dodge_roll=8

Note: There are TWO occurrences of use_dodge_roll!

One in ACTION_KEYS and one in WASD_ACTION_KEYS.

I only had one of these set, and it wasn't working until I realised.

Also, the numbers are VK Codes, which can be seen here if you want to set a different key: https://learn.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes
