how to draw a hydrocarbon chain without the hydrogenes

I am using the last version of marvin beans on mac OSX.5.

I just want to know if it is possible to draw a hydrocarbon chain, lets say pentane, so that the 3  hydrogens on both ends of the chain do not appear ? what should I do to obtain this result

 

see attachment for more explaination .

 

Hi,

Set the View > Implicit Hydrogens menu option to "On Hetero" or "Off".

See http://www.chemaxon.com/marvin/help/sketch/sketch-basic.html#implicit-explicit-H for more details.

Best regards,
