Don't know if anybody has noticed this. But after opening RTC client press Ctr+F10 and u can notice system will give small numbers or alphabets under each and every action. Just press that number or alphabet and notice how it works.
For example : Click on Sales Order link on LHS and press Ctrl+F10 and then press 1 twice a new Sales Order (equivalent to F3) form will open.
Can be given as a toy to customer, to play with.
