Yes, you'll have to create some applet files (.apa & optionally .vbs if there are scripts you want to run via toolbutton) so that you have a new toolbar. These will go in the Applets folder within your ArcPad10 folder, if they're there, they will load automatically when ArcPad starts.
To make your FORM 1 (or any form besides the editform) show when you want to edit a feature, some statement like this...
Application.Map.Layers("layername").Forms("FORM 1").Show
...can go in the "onclick" event of your new toolbutton. You can use the wizard interface within Studio to create the toolbar / buttons pretty easily, it's just the New Applet button and then once that window is open, click on the Toolbars button along the top to start adding toolbars / buttons with the wizard interface. Just like the forms they can be switched to XML view using the red / blue arrows, which may be useful for editing the toolbutton once it is created. Here's an example of a quick and dirty toolbar I created for a project recently:
<?xml version="1.0" encoding="UTF-8"?>
<ArcPad>
<APPLET name="applDocks" onload="">
<TOOLBARS>
<TOOLBAR name="Dock_Depths" caption="Dock Depths" onload="" visible="true" image="$maproll" buttonsize="1">
<TOOLBUTTON name="SelectByGPS" shortcut="" image="@gpsselect" onclick="Call SelNearest"/>
<TOOLBUTTON name="AddPoint" shortcut="" image="@modedrawpoint" onclick="Call AddPoint"/>
<TOOLBUTTON command="gpsenable"/>
</TOOLBAR>
</TOOLBARS>
</APPLET>
<SCRIPT src="Dock_Depths.vbs" language="VBScript"/>
</ArcPad>
You can see in my onclicks I'm calling scripts from Dock_depths.vbs, but you could just as easily put the code above to show the form instead. Also there's the bottom command where it's simply the normal gpsenable button, but on my new custom toolbar. If the user only needs a few buttons 99% of the time, I find its nice to have it all on one toolbar. You can add any of the regular ArcPad buttons to your custom toolbar by searching for "internal command names" in the Customizing ArcPad Help and using those command names in the same way.
Hope this helps!
