[0.17.1] CONTROL modifier assigned to mouse key is not recognized in Factorio

[Sente]

In previous versions of Factorio (v0.16 and earlier) it would correctly recognize that I had the CONTROL modifier key bound to a mouse button such that pressing CONTROL+Left Click (both buttons on the mouse) would be recognized. However, in 0.17.1, the CONTROL modifier key is not recognized when it is bound to a mouse button. I am currently using an Elecom HUGE Trackball with the control modifier bound to Fn1.

Thanks for the report.
We have multiple related report reports, so I addressed the situation in 65881

I have experienced a slightly different problem with setting the ctrl+click.

I am running on Linux, and have swapped by caps local ant ctrl keys, and 0.17 is not honoring the remapping.

This can be duplicated by running: setxkbmap -option "ctrl:swapcaps"
