Useful freeware for the Mac
For the last few weeks I have being using a couple of extensions to the “Services” menu which is available for all applications in Mac OS X:
CalcService allows you to type a formula or equation into any document or web form, and it calculates the result and inserts it into the document. Useful if you need to add up several items and add VAT to them, for example. WordService allows you to perform many different useful tasks in a document – insert the current date, or the path to a directory where a document is stored, or change the format of line feeds in a document.
Both utilities are free – recommended!
