How to change the scale in the editor?

Question

Game development

Hello everyone
I don’t quite understand how to change the scale of the scene in the editor. It is easily changed with the mouse wheel (left button + wheel), but I can’t figure out how to set it up or how to do it from the keyboard. the documentation says that it is possible through the wheel, but not a word about setting
, please tell me if it is possible to change the scale using the keyboard and touchpad (I work on a laptop without a mouse)
