Material select using with tabulator is not satisfying

Expected behavior

It should be possible to fill a form without any click of the mouse. So you type in something in an input-field, press tab, move to the material-select. The material-select should open and starts with the search field you can directly type in without pressing or clicking anything. Then move with the arrow-keys, press enter an move to the next input with the tabulator.

Even faster it would be, if you can use the material-select as the normal bootstrap select. Move on it with tab, just press in the first letters and it gives you directly a match.

Actual behavior

You have to press enter to open the material select and start to type in.

It's not possible just to type in the first letter and it will automatically chose the match.

It's not bad at all, but for me it's not perfect. I don't know if some users use it different, but when I use the normal bootstrap select, I'm way faster than with the material select, especially on the desktop. On the phone it's way better with the search function.
