[more newbie ???] howto list installed programs on menus?

[David Armour]

hello list,

i can see all sorts of instructions for installing programs, but not for 
howto list installed programs on the applications menu.
i'm looking to try out imagemagick (6:6.2.4.5-0.6) and synaptic PM 
claims that imagemagick's installed. why do some installed programs 
appear on an application menu, and not others?

i'm running dapper beta and mostly loving it. but i'd also like to fill 
in this particular gap in my knowledge base. i haven't checked the 
forums recently. my apologies if this question's just been answered.

thanks for your patience.
