I like to use my own custom ones:

• Ctrl + [ - Add internal link
  • This way I can highlight a word and make it into a note
  • Or just to save time not typing brackets
• Ctrl + Backspace - Toggle back links in document
  • So I can quickly see what other notes referenced the one I'm reading
• Ctrl + 6 - Footnote Shortcut
  • Quickly put a footnote and auto number it
  • I choose 6 because of ^
• Alt + UP/DOWN - Move line
  • I miss this so much when I'm typing in other programs
• Alt + Shift + 1/2/3/4/5/6 - Set as heading

• <ctrl-O> - to open a note. The fuzzy finder makes this super fast, if you name your notes in a way you'll remember later (SEO!).
• <ctrl-E> - switch between reader and edit mode (I almost always edit with external editor (Vim) any way, so I nearly always want the note in reader mode. In settings, you can make this the default)
• <ctrl-shift-v> - (custom binding) open current note in external editor

using vim mode with the .vimrc pluggin is a game changer. there are so many powerful vim movements; iykyk.

i also use these native commands (i'm sure there is more):

• move line up/down
  • alt+d / alt+s
• quick switcher & command pallet
  • ctrl+o & ctrl+p
• cycle bullet/check box
  • alt+c
• toggle numbered list
  • alt+n
• change view mode
  • read mode toggle = ctrl+e
  • source mode toggle = ctrl+r
• changing tabs
  • ctrl+pg up/pg down
• new tab
  • ctrl+n
• close tab
  • ctrl+w
• split view
  • vertical = alt+v
  • horizontal = alt+h
• insert template
  • alt+t
• extract heading/selection
  • alt+e
• make md link
  • ctrl+k
• toggle left & right sidebar
  • alt+a & alt+f

• ctrl+O is per default the quick finder. I changed it to the Omnisearch, because it also searched through text and synonyms

I'd recommend going into settings/options and having a look at the "Hotkeys" tab. There's a lot of things that aren't currently set, or default hotkeys that might be useful to you, like:

• Toggle pin - (not set by default) I set this to ctrl + shift + p which pins the current tab so it can't be replaced with another tab
• Close current tab - By default it's set to ctrl + w
• Command palette - opens the command palette. By default it's set to ctrl + p. The command palette is amazing because it shows you everything in the "Hotkeys" tab. So you don't even need a hotkey set to use something. Like you can open the command palette and search for "release notes" and it will show you the current release notes. If you have the emoji plugin installed, you can open the command palette and search for "emoji" and it will open the emoji toolbar.
• Quick switcher - search by note title. By default it's set to ctrl + o. But I have the Omnisearch plugin installed so I set this hotkey to that instead.

The plugin QuickAdd is really useful here as well, you can create your own hotkeys. I made one so when I press ctrl + n it creates a new note in a specific folder with today's date and time as the file name, so I can quickly write something down.

I started using the Zen community plugin for immersive writing, which I've mapped to Cmd-Shift-Z.

CTRL - P to get to all the available commands in Obsidian.

None. I mainly use obsidian on mobile.

I feel i'm an outlier in that i intentionally do not use keyboard shortcuts and focus on mouse usage instead

I'm on a mac so it's cmd but mostly the same

cmd-t - new tab cmd-up/down - move backwards or forwards in journal diary days cmd-p - command-browser (if i don't know any shortcuts i use this)
