For my OpenOffice fans, my apologies for not posting on OOo or LibreOffice for a while, however I have been working in Pages for Mac recently.
Just a quick tip as much for my own reference as for anyone else’s – for some reason I keep losing this reference.
Changing the case of letters in Pages is possible by selecting Format –> Font –> Capitalization. You can then choose the capitalisation you wish, keeping in mind that this will not remove capitalisation. (eg it will not change ‘THIS’ to ‘this’)
At the moment, it appears the only way to remove CAPITALISATION is to copy and paste the text in TextEdit and use the Edit –> Transformations menu option.
