Where and when does TypeIt4Me type?

The “typing” (actually a “paste” operation) will occur wherever you are currently entering text, be it in a word processing document, a Finder Get Info box, a Save as... dialog, a folder or file name field, a database entry field and so on.

The text (and/or image) stored in one of the clippings will be pasted at the cursor location for you either when you select its name (i.e. the abbreviation you have defined) from TypeIt4Me's menu or when you type its name (optionally) followed by any of up to 33 trigger characters. Using the Settings tab in the TypeIt4Me panel of System Preferences, you can define exactly what characters should act as triggers (or choose to have no triggers, in which case your abbreviations will expand as soon as you type them).

Unless the clipping is defined as “Rich” text, the font and style of the text will be those currently applied to any text you may type yourself in your document, not the font and style that the text was in when you defined the clipping.
Similarly, the location of the text will be affected by the current ruler settings in your document.

Note however that the "typing" will actually occur by placing the clipping text on the Clipboard and issuing a Paste command. If TypeIt4Me ever seems to fail, try doing a "manual" paste into the field and see if that works. If it doesn't, then you need to contact the manufacturer of the software and ask them to support pasting into the field in question. For example, you cannot expand an abbreviation in the Save as dialog that follows a Save as PDF in the Entourage Print dialog, while the same operation does work in TextEdit and Mail.

Also note that some password entry fields are protected against programs trying to "sniff" what you type into them. Safari is one such case and typing an abbreviation in a password field in Safari will NOT result in expansion of the clipping. However, not all is lost as you can define an abbreviation to type your username in the field you type it in, then issue a TAB to move to the password field and finally issue a paste to place the password there. If you also include a CR (Carriage Return) after the password, it is likely that the OK or Enter or Submit button will be invoked.
Note that the TAB and CR in question must be entered in the clipping via the Insert/Special menu:
