1. the distance following the cursor does not display any decimal reading: does one need to go to some setting to specify the number of decimal point? if yes, how can i do it? My measurement is set to 3 decimal points. Use the ""Page Up"" and ""Page down"" keys during the operation to change the number of decimals for this. Use ""home"" to reset it. 2. the adaptive grid + key shortcut: I can not experience the benefit of this key shortcut , I believe that the problem I have in (1) needs to be solved first. Not sure what you mean here, more detail would be great.
