I am working on a laptop (thus I don't have the numeric pad). To erase a cell in Mathematica I always have to look on the right of the notebook window to find the bracket associated to the line, and then push del on my keyboard.
This is really inefficient because I always have to be carefull to erase the proper cell.
Isn't there a way to directly erase a cell by selecting its text and pushing a given key (selecting text + del will delete the text but not the cell).
Also, my keyboard is AZERTY (French keyboard).
