Joining two parts of one object.

Is there a faster way than manually selecting vertices and merging them? I’m looking for something like the boolian modifier but for separate parts of the same object.

I’m making meshes from text and the bevel and extrude used in the text editor creates multiple parts when converted to a mesh.

Perhaps there is a way to keep it in one piece on conversion?

Please show an example to clearly demonstrate what you are actually talking about. Please include both screenshots with annotations and an example blend file

Text with extrude and bevel.

Converted to mesh.

Results in three separate pieces in one object.

I figured it out.

Select all vertices>Remove doubles

I did not have all selected when trying this before and the tool tip for functions are rather vague.
