<p dir="auto">I'm having issues giving keyboard focus on Button when the component is button (this is important for supporting on-screen remote controls for TV). I'm trying to set it to anchor / a-tag instead, but the documentation is using this "Link" object, which only exists in the documentation's sources.</p>
<p dir="auto">In addition, just pulling that file into my own is showing another dependency on "NextLink" which I can't find anywhere at all.</p>

<ul class="contains-task-list">
<li class="task-list-item"><input type="checkbox" id="" disabled="" class="task-list-item-checkbox" checked=""> I have searched the <a href="https://github.com/callemall/material-ui/issues">issues</a> of this repository and believe that this is not a duplicate.</li>
</ul>
<h2 dir="auto">Context</h2>
<p dir="auto">see above - I need :focus and autoFocus to be always working in button for using a TV remote control, and that doesn't seem to happen when I use button. trying to use anchor tag but the documentation is not helpful.</p>

<p dir="auto">nothing else is relevant.</p>
<p dir="auto">The animations for indeterminate/query modes do not loop properly. Basically the animation ends empty and starts half-filled.</p>
