How to automate send keys operations in applications launched via citrix

trying to automate clicking of few menu options (ALT+F, ALT+W) in one of application which is launched via citrix. process does not work on citrix applications, while same process works on normal applications (i.e. Chrome, IE etc). Is there any limitation from product side for send keys automation on citrix applications.

HI,

Send Keys only work on active desk top window. On remote machine it will not work
