How to read selected text in shell command (Ctrl+b)?
Something like:

In a plugin you can use the Cursor.GetSelection method to get a selection from a cursor:

function getSelection(bufpane)
    local cursor = bufpane.Buf:GetActiveCursor()
    local selection = cursor:GetSelection()
end

Keep in mind there may be multiple cursors, and the code above only handles one. You can probably find the methods you need to handle them how you want in the internal documentation.
