On mobile, there is no option to select all below. On desktop you can use control-shift-end or control-shift-down but on mobile there isn’t such capability. Currently you have to scroll select and depending on how long the document is, it may take a really long time. Not only that, there’s always a chance the select may become undone accidentally or get stuck and you’d have to restart.
Proposed solution
Can select all below button be added to the toolbar or something.
workaround on android / google keyboard: press the “<I>” text editing button found in the buttons menu, make sure “select” is enabled and press the “>|” end button.
I’ve tried both but each have their own issues. what it’s sticking and keeping me in flow is the “Extract after cursor…” command from Plugin: Advanced Note Composer give it a try. (if you only want to select simply cancel the operation before typing the destination)
