I’ve just tried it but I’m stuck 
I’m using doom-emacs and do SPC :term then I ssh into the server with my usual alias, then when there I navigate to the directory which contains the file I want to open. If I press escape and then SPC I am shown:
If I press . I am only shown my local files, but I want to open one of the files from the server - is there an easy way to do that after having navigated to the folder as I have above? Or can I only open a file as per the video where you must already know the file name and location and use the path while ssh’ing in (in which case it’s not much use to me as it’s much easier then just to ssh into the server normally).
