I want to make a line ...

[Cyrille0D45]

I'm still looking with Photoshop 22.1, how do you make a red two-dot line with a thickness of 3px and a white outline of 2px? With two clicks and with the mouse, please. In addition, this method must be compatible with all versions of photoshop.

What you are describing sounds like a rectangle, not a line (what with having an outline of its own). 

And the procedure you describe would not even be met in older versions, I think – the line Tool didn’t work with »click-click«, but »click-drag-release«, didn’t it? 

»this method must be compatible with all versions of photoshop.«

Not all versions of Photoshop supported Layers, so please be more specific. 

One work-around (that would naturally only work for Photoshop Versions with Shape Strokes) might be

• setting the Path Tool to »Shape« 

• setting the Stroke to the desired settings 

• creating the Shape Layer within a Group with the Layer Style Stroke 

Another option would be »borrowing« a Tool like the Count Tool and using Script Events Manager to link it to a Script that created rectangluar Shape Layers every secong click, so to speak.

Juste clic clic ...

The Line Tool has been changed in Photoshop 2021 – deliberately or accidentally I don’t know …

What’s this about anyway? What is this for?

I make montages with multiple layers with guides, arrows and lines.

I suspect you might be better served with doing such annotations in Illustrator.
