What is this G button function in blender called(happens in Edit mode)? https://www.youtube.com/watch?v=dGVMXyZNCQY


My shadowplay is acting up so its low rez for some reason(i set it as 720p)...

Basically if you recreate the rentancle(i had to do it for my project model i am working on) and press G button multiple times in edit mode(but in order for this to work you have to select same edges i had).

What is this blender function called? Is it similar to google sketchup follow me function?

If your edges turn yellowish, this is the function i got/found and i cant find any info on it....
This is the Edge Slide function. Selecting an edge and pressing G two times will enable this. It allows you to manipulate edges along other edges, scaling then accordingly to maintain the overall shape while moving the edge. An example can be seen below on my mesh:



Hope this helps.

EDIT:
On your video, in the bottom left corner, you can see you have "Vert Slide" enabled. This works similar to Edge Slide.
