HP-49G+ indefinite integration

[pivoneer]

I've just upgraded to HP-49G+ from my old TI-89 machine (hello there!) and now am going through the user's guide. I've currently reached the end of "Creating and editing summations, derivatives, and integrals" paragraph and can't find any proper description of entering indefinite integrals in Equation Writer in "pretty" form. I briefly went through other "integral" enterings throughout the document, but all I could find is terminal input way with INTVX() CAS command; however, this method is not so graphically nice and also doesn't allow to change integration variable (I guess only through CAS settings in MODE menu, which I find inconvenient).



For example, to enter indefinite integral on TI-89 in Equation Writer app, you enter basic definite integral and then just erase any of two limits - integral will become indefinite.
Is there any similar way to achieve this on HP-49G+? Or I'm just missing something?
