The screenshot attached doesn't show the mouse location, but I am hovering over the Acrobat PDF icon in the grid and the tooltip shows "Export to Excel". Clicking it exports to Excel.
Hovering over the CSV icon shows the tooltip "Export to PDF" and clicking exports to PDF.
Hovering over the Excel icon shows the tooltip "Export to Word" and clicking exports to Word.
This doesn't happen when using the Metro theme; only Bootstrap...maybe others, but I'm only using these 2 themes.
