if you mix ordered and unordered lists and sublists, for example
Item
subitem
subitem
Item
subitem
subsubitem
subsubitem
subitem
When you press enter after a subitem, Obsidian automatically puts a new subitem but if you press Alt+Tab to make the subitem an item, Obsidian doesn’t recognize that it should be an ordered item and it still uses the dash.
I see what you mean. Here is a gif showing it in action.
I don’t know what you mean by “alt-tab”. Did you mean “shift-tab”? I guess that depends on your OS and keybindings.
If you un-indent an item, it adopts the format of the sub-list you were in, instead of the format of the latest matching item of the new level.
Line 16 is a dash, at level 2.
Line 17 and 18 are numbered at level 3.
On line 19, when I un-indent back to level 2, it would be nice if it matched the last-matching level 2 formatting of line 16 (dashes). But it continues to match the level 3 formatting of line 18 (numbers).
