How to paste one by one?

How to paste things like this:
1

paste one by one,no need drag.

Hi there! One possibility will be using the custom brush command (Ctrl+B, Edit > New Brush), or other option would be:

  1. use Ctrl+press mouse button in the selection
  2. then press Alt key while dragging to snap to grid the moving selection,
  3. and finally drop the selection

This might be done with some kind of script too (so one keystroke could copy the selection at the side). But not sure if you need this to be automated or the drag and drop solution is enough.

Dude,thx your reply.
I asked a guy in youtube, he told me Ctrl+V to paste texture, then Shift+arrow key can snaps the texture to Grid.
