The “Rename this heading” command is only available whenever the carat is on a heading already, limiting its convenience.
Proposed solution
Allow for the command to always be usable, and presume that the user wants to rename the closest header above (i.e., the same header as the outline would highlight).
Not a solution but you can use Code Editor Shortcuts community plugin and Go to next heading and Go to previous heading shotcuts. You can use the same shortcuts for navigation or editing.
Thanks, I forgot about it. Now I’m going to create a macro cause it’s really annoying manually placing cursor on the heading above, specially on mobile.
Here are macros in practice (QuickAdd/community plugin):
Obsidian CLI can be used to create macros but currently its use is mainly limited to external terminal or 3rd party automation tools (PowerToys, Shortcuts, Raycast etc). One plugin, namely Shell commands, brings shell scripts inside Obsidian so that you can access them via command palette etc. This can be useful because shell commands can read context implicitly (what file is open etc).
