The Tool Options should be visible all the time (and docked). It get used all the time.

Select the Text Layer. Select the Text Tool. Click on the text. Now check/uncheck the anti-alias box.
Better, set the anti-alias option before typing your text.

Quote:it was mentioned about dpi

A bitmap image only has pixels. The dpi only comes into play when printing (for example) on paper. Then dpi depends on the image size in pixels and the print size in inches.
For the web, setting dpi has no effect.
