You can do this if you use Chrome. Open up Listary’s options. Go to “Keywords.” Add a keyword, with the following:
Display Title: Open Chrome Tab
Then, quit and launch Listary.
To use it to open cnn.com, for example, type:
And it’ll open a new tab in Chrome and load cnn.com in it.
I believe that you should be able to do the same with Edge, Firefox, Opera, et al.
I hope this helps!
