On some softwares you can have more than 500 shortcuts. The use of a large number of shortcuts leading inevitably to their complexification and makes them hard to remember for users especially for casual users.
What if your smartphone can directly drive your computer software through these shortcuts ?
As a developer, I often use special characters such as [ and ], #, |, ` or \. All those specials characters are written with the "ALT GR" key (named "AltCar") on my keyboard. For a # you need both your two hands because the "3" key is far away from "AltGR". The idea is to control this key using my right feet.
