Trying to use fn + control + left / right to tile the Obsidian window in macOS Sequioa. However, these keys first scroll the window to the top / bottom, like how the Home and End keys work in Windows. So, I have to first let Obsidian scroll to the top / bottom of the current note, and then repeat the keyboard shortcut to send the Obsidian window to tile left / right as desired.
command + up / down jumps to the top / bottom of the content in a window in Obsidian as in other apps. Good.
function + left / right scrolls smoothly to the top / bottom in other apps. But only moves the cursor to the beginning / end of the line in Obsidian. Ironically, if you search these keyboard shortcuts in Obsidian Hotkeys, they show as Home and End. They just don’t act as Home and End should.
When I remap control + option + F in Mac settings (to the new Mac window tiling command Fill), this remapping works in other apps, overriding the system default of move cursor forward one word. However, in Obsidian the system default is still in effect. In TextEdit, my remap is respected. In Obsidian, it is respected when the cursor is not in a text field. To get some of my other key maps to work in Obsidian, I had to delete existing hotkeys. But there is no hotkey for control + option + F . It just seems that Obsidian parses key map configurations in a different order. Unless I am mistaken, Obsidian is prioritising the system default key map before any custom shortcuts set in Settings / Keyboard / Keyboard Shortcuts… / App Shortcuts.
So I just remapped keyboard shortcuts in the system settings (settings > keyboard > keyboard shortcuts > app shortcuts). You can’t bind the shortcut with pretty much every modifier key + left/right, because Obsidian will prioritize moving within the text if the cursor is active. As for myself, I mapped left tiling to control + ; and right tiling to control + “backslash” (at least those are the symbols on english keyboard, I think, I have mine localized). Basically, you can remap It to whatever you want if It does not interfere with Obsidian or other shortcuts and build on It and remap the Fill for instance.
Keep in mind these are just my observations, I started solving this issue only today. So feel free to ask any questions if you are uncertain about something.
