To switch multiple map by the Kashmir, use following functions rather than selecting [File] - [Open] - [Map].
(1) Select from the last used map
Maps once used are listed under the [File] menu.
Select the map just from the menu.
(2) Using [Jump] Menu
Selecting [Jump] - [Mark Current Map] enables registering the current map in the jump menu. Enter the reasonable title for the next use.
