If this variable is @code{medium} (which is the default), a number of
checks will be performed. If as result @acronym{NSM} determines that
-the network connection might be unsafe, it will make you aware of
-that, and will ask you what to do about the network connection.
+the network connection might not be trustworthy, it will make you
+aware of that, and will ask you what to do about the network
+connection.
You can decide to register a permanent security exception for an
-unsafe connection, a temporary exception, or refuse the connection
+unverified connection, a temporary exception, or refuse the connection
entirely.
Below is a list of the checks done on the @code{medium} level.
connections are being hijacked by agencies who have access to pliable
Certificate Authorities which issue new certificates for third-party
services, you may want to keep track of these changes.

+@item Diffie-Hellman low prime bits
+When doing the public key exchange, the number of ``prime bits''
+should be high to ensure that the channel can't be eavesdropped on by
+third parties. If this number is too low, you will be warned.
+
+@item @acronym{RC4} stream cipher
+The @acronym{RC4} stream cipher is believed to be of low quality and
+may allow eavesdropping by third parties.
+
+@item @acronym{SSL1}, @acronym{SSL2} and @acronym{SSL3}
+The protocols older than @acronym{TLS1.0} are believed to be
+vulnerable to a variety of attacks, and you may want to avoid using
+these if what you're doing requires higher security.

A more convenient graphical way to specify the slice is with @kbd{s
m} (@code{doc-view-set-slice-using-mouse}), where you use the mouse to
-select the slice.
-@c ??? How does this work?
+select the slice. Simply press and hold the left mouse button at the
+upper-left corner of the region you want to have in the slice, then
+move the mouse pointer to the lower-right corner and release the
+button.
The most convenient way is to set the optimal slice by using
BoundingBox information automatically determined from the document by
-typing @kbd{s b} (@code{doc-view-set-slice-using-mouse}).
+typing @kbd{s b} (@code{doc-view-set-slice-from-bounding-box}).

To cancel the selected slice, type @kbd{s r}
