# Linking Window
**Description**
Linking windows enables you to view a lot of information on many instruments quickly without having to open any new windows. Type the symbol code or double-click on a symbol to change the content in the linked windows.
**Link windows one by one**
Open the window you want to link and click on the link icon in the window caption. Do the same to all windows you want to link together.
The linking icon now displays the channel they are linked on. By default it is channel 1.
**Link windows by channel**
To create different groups of linked windows, use one preferred channel for each group.
**Link all channels**
If groups of linked items are needed in addition to having some windows linked to everything; the "All channels" selection can be used for those specific windows.
**Example**
The channels do not affect one another.
Double-clicking on CARL B in the custom list, will change the chart and the orderbook to show data for CARL B.
Double-clicking on JPM in the market window, will change the historical prices to show data for JPM.
