plain text editor that can delete lines I keep to do lists on my computer using plain ASCII text (.txt) files that I sync with Dropbox.

I just got an Android tablet and I'd like a text editor that I can use to edit those files.  I need only two features above the basic text editor:


Ability to delete a line (the ability to select a single line would also work)
Ability to move a line up/down one line (this one is optional)


Any Android text editors good for lists?
I find Epistle a useful text editor that syncs with a Dropbox folder, it's not the most advanced editor but can handle both plain text and Markdown formatted plain text (as used here). It uses the built-in Android text selection features, so you can select a line by dragging the text selection arrows to both ends.
