Documentation: missing shortcut that opens the account list in a register

[Paolo Benvenuto]

As we are working on documentation, I suggest that we put again into the 
shortcut paragraph the shorcut that unfolds the account list in the register. 

This shortcut was documented in 1.6.x docs, but I can't find it in the 1.8 
ones.

Buon cammino!
