Yes, although I recommend against using /c/ because it doesn’t actually link to the community. I also recommend against typing out the full URL (e.g. https://lemmy.ml/c/asklemmy) because it might cause issues for people in different instances.
The proper way to link to a community is !communityname@domainname.tld. For example, !asklemmy@lemmy.ml

What are you doing with your keyboard one-handed? I can’t think of any real use for one hand on a keyboard aside from gaming and shortcuts like copy+paste. And this keyboard runs QMK so it’s very easy to just remap any shortcuts that the split might make difficult.
Screen record a video of the process? Then you’ll have a video guide, plus you can take screenshots of the video for a written guide.
