CTRL + A Menu Apply Transformation : where to find in Python document I noticed that very often when I search for a command or something in the Blender Python API I do not find what I am looking for. I am not sure if I simply make a mistake or if what I am looking for is not available.

For example:

CTRL + A calls the Apply Transformation menu


I am after the command "bpy.ops.object.transform_apply()" but I would like to make a button that opens that menu.

And what calls that menu is not what I am able to find.

Can anyone give me a tip where such information is in a document?
For this one ( or other shortcuts ) :


go to User File -> preferences -> Input 
search for a key combination  "Ctrl  A"
expand the shortcut for "call menu" under "Object mode"
you can see the command is "wm.call_menu" and the name attribute is "VIEW3D_MT_object_apply"


since the shortcut point to an operator which should be under "bpy.ops", we use this line to call the same menu  :

bpy.ops.wm.call_menu(name="VIEW3D_MT_object_apply")
