Working environment (roughly)
iPad third generation
Crysta Paint EX2024/03/28 latest version,
logitech bluetooth keyboard k380

When changing the name of the material for changing the layer name,

1. Change the layer itself in the layer window by double-tapping, etc.

2. Menu → Layer → Layer Settings → Change Layer Name (A popup for changing the layer name will appear, and you can set it inside) Route (I usually set shortcut keys for...)

I think there are two ways,
In case 2, the keyboard does not respond.
I'm trying to compromise on the worst option, but

In a similar case,
A similar pop-up is displayed when a material is renamed, but it also does not respond.

As far as I know, there is no other way to change the material name, so as a last resort I disconnected the keyboard and entered it using the iPad's on-screen keyboard.
I'm starting to think this is a hassle.

I don't change the material name as often as I change the layer name, but... (Maybe it's because I can't use the keyboard when it pops up...? When I think about it, I think there are other similar cases...)

Is there anyone who is having similar trouble?
If you have any other solutions, please let me know...
