In the file manager you can see the files you have uploaded and the
lists you have created.
</p>
<h3>Searching</h3>
<p>
By clicking the search bar or pressing the / button you can search
through your files or lists. Only the entries matching your search
term will be shown. Pressing Enter will open the first search result
in a new tab. Pressing Escape will cancel the search and all files
will be shown again.
</p>
<h3>Bulk actions</h3>
<p>
With the Select button you can click files to select them. Once you
have made a selection you can use the buttons on the toolbar to
either create a list containing the selected files or delete them.
</p>
<p>
Holding Shift while selecting a file will select all the files
between the file you last selected and the file you just clicked.
</p>
