How can I change the font size of the email listings in my Inbox?

One of these SHOULD? help..... Easiest way is to hold down the CTRL button...lower left..and rotate the wheel on your mouse...MORE OPTIONS 1. If you are talking about the text in your email... When you compose an email above the text box where you type an email you find a tool bar. If it is not there then CLICK on RICH TEXT and PLAIN TEXT should appear with the tool bar. 1. Select the text for which you want to change the font 2. Now click the font button (F, second in the toolbar) and u get the list of available fonts, select the one you desire. 3. you can also change the text size using the same toolbar. move you mouse over each button to know what it does. well this is i how you change the font while composing an email. If you are asking about changing the fonts of entire yahoo email view try clicking on TOOLS at the top of your screen and then CONTENT. Depending what Yahoo you are in...IE:Firefox..you might have to click on Tools..Internet Options and then CONTENT...You can do many things with the FONT. You will have to experiment And if you really want to fool around try this....Once in click on HELP and it explains many things on how to use it... Click the "start" button on the lower lefthand corner of your screen. Click "run", enter "charmap", it will show all your installed fonts and the available characters and wingdings for each font. Try "arial", click on the character you want (it even contains musical notes and little hearts). You may click on a specific character to enlarge it slightly and by "copy & paste" you can insert it in any text you want to. On the bottom of the charmap window it will also let you know which keystroke to use for writing that character good luck ....Have a great day...................
