How to remap CapsLock as a toggle?

Question

Programming

The laptop has a shorter keyboard.
Since I type blindly, I want to work without taking my hands off the positions of FYVA and OLJ.
For example, I typed the text, then you need to correct a word and use the arrows to move the cursor to the beginning or end of the paragraph. At the same time, I take my hands off the original position and transfer my right hand to the arrows, which is very inconvenient for me.
How to make when you press the CapsLock key - some keys take on other functions, for example, as shown in the picture below:

Where:
Yellow - become navigation keys
Red - become numeric keys from 0 to 9
Blue - CapsLock serves as a switch to the "Yellow" mode -Red" and back to normal.

I have not tested this advice myself. But I understood what can be done in Windows using the SharpKeys utility .
