When adding new rows or doing other chores with a table, it is often easier to add a new row with a button than from within the table or using the plus symbol, in particular when the table is long. What I am missing is a good way to access my buttons from the keyboard.
There are a couple of things that could improve that: if the (Shift)tab key could be used to jump from table to button, from button to button, etc., it would improve things quite a bit. Also being able to mark a letter of the label of the button to activate the button with the Alt-‘marked letter’ (or an optional setting in the button to do the same) would make working with coda a lot easier.
