How to add a specific amount of loop cuts without the mouse I am working on a blender project where I have a cube in which I want 14 loop cuts.
Blender 2.8 can do exact loop cuts with scrolling the mouse.
My Question is: Can you do this without a Mouse?
Yes you can. Here's how:

with the element selected, hit → Tab
hit ⎈ Ctrl + R and hover your mouse to activate the loop visualiser
hit 5 (if you want 5 cuts)
hit ⏎ Enter
enter a number between -1 and 1 to define the offset of the cuts, or use the arrow keys to move them in increments
hit ⏎ Enter
