How to make available commands for write :w file and read :r file ?

[hberge]

In vim I often mark up some text and use :'<,'>w filename to write the selection into a different file.

I think that would be very useful with notes as well, for example when there is some part of a larger note that I would like to put into a smaller note and include by reference instead.

How can I write .vimrc commands to support this behavior?

Second in line, if someone can help me or point me in the direction of how to get the above to work, I would appreciate the ability to read in notes as well. E.g. :r Note name should read in the note with that name/reference.

---

Third. If I will be able to read and write notes I will also, typically, want to put them in folders. So therefore I would really appreciate it if the commands :pwd and :cd, so these can have an influence on where the :w command writes files.

---

Last. Tab-completion or some other ideally fuzzy find mechanism that can work with :r. Ok, that is outside of what I'm asking for this. Unless it's actually really easy.

Just to let you know! I'm enjoying obsidian vim mode very much and very happy to see vimrc support! Thank you so much for making this! 🥇
