$dotoolmethod $dotoolmethod(iToolId, cMethodName [,method parameters]) calls an external method in an environment tool
$installtool $installtool(iToolId [,cAddInMenuText, iIconId, cAddInMenuHelpText]) installs tool library on tools menu and toolbar; returns non-zero for success (for add-in tools value is config item base)
If iToolId is kEnvToolAddOn, $install tool installs an add-on tool, on to the tools menu in the IDE. An add-on tool is an Omnis library which provides some additional functionality to the IDE; for example, the string table editor is implemented as an add-on tool. You place a library implementing an add-on tool in the Startup folder of the development version, and then install the tool in $construct of its startup task, by calling $installtool. 
cAddInMenuText is the text which appears in the add-ons menu; iIconId is the icon id of the icon used for the menu line for the tool; cAddInMenuHelpText is the text which appears in the help bar when the menu line for the tool is highlighted. 
$installtool() returns a non-zero number for success. The tool can use this number as the first of 200 possible configuration item numbers in omnis.cfg, accessed using the configuration methods described for $root.$prefs. The number will be the same each time the tool installs itself, provided it does not change the menu-line-text; if you delete omnis.cfg, you may get a different number, but this does not matter, since you have also lost any configuration information the tool may have stored. 
When the user selects the add-on tool from the menu, Omnis calls the method $exectool() in the tool's startup task. This typically opens a window, or brings it to the front.
$welcome $welcome(kWelcome...) executes a request from the welcome library
