For me, it’s about knowing the mnemonic for the various vim commands and what the keys do, not where they are placed on the Qwerty layout. I’ve been touch-typing Dvorak for over 20 years and think about what I am trying to do in vim/vi (or evil-mode) rather than where on the keyboard I need to hit a key.
A quick duck search pointed me at https://toolsweek.com/how-to-test-a-diode-with-a-multimeter/ . It’s been a long time since I needed to test diodes, but the instructions seem to match what I’ve done before.
If you choose SPC < to bring up the window that shows all open buffers, you can choose it and hit SPC b k (buffer, kill) as !GameWarrior@lemmy.world suggested. You can also choose SPC b d (buffer, delete) which is the same as SPC b k, or just hit SPC b and look at the options available to you.
