TL;DR
When you open the "Select a signal" window (while setting a condition), automatically place the keyboard cursor into the "set a constant" number box.What ?
This is a small quality of life change that does not affect gameplay mechanics. When manually assigning conditions for many combinators (or other), it gets tedious having to add an extra click to each one. This could also be applied to setting train conditions, when you select a condition that takes a number value it should by default move the keyboard cursor into the number box. Also, when it selects the box, highlight the current value so it can be overwritten, instead of the current where if there's a 0 in that box, you add numbers following the existing zero.![Image](https://forums.factorio.com/images/ext/dae2ddc74bb366bbede4c65d17e87414.png)
