Shows information about Localizer.
Move menu
Zoom In
Zoom Out
These buttons put the Map in Zoom In and Zoom Out modes respectively. By clicking in the map, you'll get a bigger/smaller view of the place. Keep the mouse/stylus pressed and you'll zoom more. It's also possible to move in order to pan around the map.
Top View
Allows you to see in a glance the whole place by setting Zoom to 1:1 (1 meter in reality is 1 pixel in your device)
Set Your Position
Puts the map in a mode where you can specify your position by clicking on the map wherever you are. This is useful to know in the search dialog the distance there is from you to any place, or to easily go from where you are to some other place (longer explanation in a later section).
Go to Your Position
You may have been looking at the map for so long that you don't know anymore where you're looking to. In that case, click in this item to make Localizer show you exactly where you are (given that you didn't walked a lot since you last selected "Set Your Position"). In case you're really lost, read the section on How to Move around.
Search menu
Search Marked Items...
Same than above, but only shows you the items that you marked (which are, presumably, the places you're interested in going to).
Look Up Map
Puts the map in Look Up mode so that when you click on any place, you're shown an information dialog which will tell you what's that.
Options menu
Show Arrow when Searching
When you make Localizer show where something is (by clicking on the "Go" button in the information dialog of a company for example) and you move away, the map will show you an arrow pointing in the direction to that place. There are few reasons why you'd like Localizer not to show you the arrow (just because the map drawing is slower when the arrow is painted or because you simply don't like it). In that case, you can enable/disable it from this menu item.
Show Large Icons
Use large icons for the toolbar or normal (small) icons
Drag to Move
When set and you're in Pan mode, you have to click the screen with your stylus and move it, like dragging the map with the stylus. When "Drag to Move" is not set (the default), just clicking on the screen makes it move the map towards the direction the stylus is pointing to.
Draw Building Borders
This is specially useful for city maps (like example 4). In that case, if you want to look at a map without all the borders of the relevant buildings and places, just unset this option and you'll have a look
at the map without any overlayed image. Set it again to see where the relevant buildings are.
The company information dialog shows the company name, information on what the company does, the web page, etc. Also, it includes a list of representatives from that company who will be at the show, together with their charge within the company and their email address. There's also a list of presentations that this company will do at the show (with respect to some new developments or a new product for example). Double clicking on a presentation will show the presentation dialog, where you can see more information about it, set an alarm for some minutes before it starts, or make Localizer show you where the presentation is held.
