Hi, I just compiled UE4.8.3, I’m using Ubuntu 14.04 and the command CTRL+W is not working on the materials editor, It works in the viewport though, also copy paste is not working (I tried to copy the nodes to a text editor and there is no output).
I edited the keyboard shortcuts for the material editor, and nothing happens, Is this a bug or I’m missing something here??
Never mind Version 4.9.0 has this bug on GNU/Ubuntu fixed 
, I’m getting more addicted to UE4 on Gnu/Linux, awesome.
