Option to merge double vertices?

I am new to this forum, so I hope this is the correct place to write :wink:
I’d be interested whether there is a option in blender to merge two (or more) vertices that are at the same position, as I’m quite often facing this problem.

Note: The tutorials forum in for COMPLETED tutorials only, not for support questions, that’s why there there are all the other support forums split into different subjects

Moved from ‘Support / Tutorials, Tips and Tricks’ to ‘Support / Basics and Interface’

Select vertices and use Mesh / Vertices / Remove Doubles https://www.blender.org/manual/modeling/meshes/editing/basics/deleting.html#remove-doubles

Change merge distance if required
