@Cezary Szadejko (cez): It's still alive but still waiting for issues to be solved with left click described here: T57918. Now that left click is enabled by default, it's paramount that we tackle these remaining issues anyway, and that will also pave the way for keymaps such as this one.

hi, Addons are specifically designed to interfere as little as possible with Blender default keymaps. They are also iirc, loaded at start up. You are using custom keymaps which can fall outside the scope of addons design and default key mappings at the moment. I feel that what you are requesting is outside of addons/keymap current design. To get around this you can edit the individual files that give you trouble with your custom keymap. I'm not sure this is a bug or a feature request or simply a limitation of the current design and the way things work.
A more knowledgeable blender developer may correct me if I'm wrong here.

Not sure if I understand correctly:

The Weld tool will move selected UVs to their average position, they will remain separate entities though.
If you weld two UVs that are slightly apart then these will hop into the same location [thats what you call "it works"], but you can still select one or the other, no?

So, unless I am misunderstanding something, two UVs can never be made into a single one.
