Problems entering literal from LWC11 Tutorial

I'm using MPS 1.5 now and trying again to work through Markus's tutorial and cannot figure out how to enter the following literal:

if( link == /link/EntityAttribute : type/)


After I type the slash, MPS seems like it wants to perform division.  Is there some trick to this, or did I skip an important step in the tutorial?

Thanks,
Jeff

hi,

after typing link ==  (and waiting that the editor recognized it correctly) use code completion to select the

/link/<role>

entry. that s it..

Thanks Dan; I had already tried that and it's not available.  I hadn't gone through the tutorial sequentially, so I'm wondering if I might have missed an important step?

There's something that's somehow either corrupted or configured wrong in the project.  I went to another project and created a simple empty concept and had no trouble entering it.  

I'm not sure, but I may have started this project in MPS 2.0 before I was advised not to use 2.0

Maybe I'll try starting the tutorial over.

I did notice the following IDE error that may or may not be related:

This class was added in MPS 2.0, so most probably you are trying to "downgrade" MPS :-)
Don't do that and simply create new project in MPS 1.5 if you need it.
