Click on the Telnet bookmark. 

Telnet bookmarks can use a port designation for servers not running on the default port.

Cursor shape updates Enable

Cursor  shape  updates is a protocol extension used to 
handle remote cursor movements locally on the client side, 
saving bandwidth and eliminating delays in mouse pointer 
movement. Note that current implementation of cursor 
shape updates does not allow a client to track mouse cursor 
position at the server side. This means that clients would not 
see mouse cursor movements if the mouse was moved 
either locally on the server, or by another remote VNC client. 

Set this parameter to Disable if you always want to see real 
cursor position on the remote side. Setting this option to 
Ignore is similar to Enable but the remote cursor will not be 
visible at all. This can be a reasonable setting if you don't 
care about cursor shape and don't want to see two mouse 
cursors, one above another.

Use CopyRect

Yes

CopyRect saves bandwidth and drawing time when parts of 
the remote screen are moving around. Most likely, you don't 
want to change this setting.

Restricted colors

No

If set to No, then 24-bit color format is used to represent 
pixel data. If set to Yes, then only 8 bits are used to 
represent each pixel. 8-bit color format can save bandwidth, 
but colors may look very inaccurate.

Mouse buttons 2 and 
3

Normal

If set to Reversed, the right mouse button (button 2) will act 
as if it was the middle mouse button (button 3), and vice 
versa.

View only

No

If set to Yes, then all keyboard and mouse events in the 
desktop window will be silently ignored and will not be 
passed to the remote side.

Share desktop

Yes

If set to Yes, then the desktop can be shared between 
clients. If this option is set to No then an existing user 
session will end when a new user accesses the desktop.
