Thanks for your response, Dominik. I use a Mac, where the zooming keystroke is CMD plus '+' or '-'. This works fine, unless I am actually editing text within a text frame, where it does not zoom. I have to click on the page elsewhere, but not in any text frame, for the zoom to work.
The issue with the paragraph returns is strange. Within any paragraph of typing, the DELETE key deletes text, and paragraph returns, in the normal way. But if I come to the start of a paragraph and go to delete the paragraph return linking the text to the previous paragraph, it will not delete unless I actually select that paragraph return symbol and then press DELETE. Does that make sense?
