Can't find "Play" button

[putztzu]

Windows 10 Build 10240
Calibre 2.77.0 (64-bit)

Installed the plugin (is listed in Calibre)
Open a book (mobi format if it makes a difference)
There is no obvious "Play" button or something similar anywhere that can be found.
Have also tried to highlight text and press "Enter"
Have tried both "Flow" and "Paged" modes.

I finally was able to get this to work by inspecting the plugin's settings and found that the default keystroke combination is "CTL-space" which works.

Hoping anyone who has successfully installed this plugin can post a screenshot where the "Play" button and any other controls is located.

Thx.

It's possible that your window isn't large enough - it's underneath the print button, you might need to press the expand button on the toolbar to see the last few items. Or try resizing your ebook window to be larger.
