Eyes tired from small font? Are you using your reading glasses more and more often? One solution is to enlarge your browser font and page size. All the browsers have a zoom feature in the menu tools, but keyboard shortcuts are the easiest to use. There are subtle differences between browsers as to new pages keeping the zoom or reverting to the original 100%, and to wether you can zoom only the font and not page images.

The Opera browser is the only browser to use just a single key. Just tap the "+" or "-" keys in the top row (or numeric key pad) to zoom in or out. It changes not only the page size but any fixed image size. You can also use the "0" or "9" keys. Any daughter pages from the zoomed pages are also the new size. Any new URL page will be at the 100% size.

The Firefox browser can zoom the page size by using the control key with the "+" or "-" key, ie. "Ctrl +" or "Ctrl -". It also has a menu item to just zoom the text. Any daughter pages from the zoomed pages are also the new size. Any new URL page will be at the 100% size.

The Google Chrome browser also uses the "Ctrl +" and "Ctrl -" keys for zooming in and out. It does not show you any shortcuts in the menu, so how would you know? Any daughter pages from the zoomed pages are also the new size. Any new URL page will be at the 100% size.

The Safari browser also used the "Ctrl +" and "Ctrl -" keys for zooming in and out. It also can be set to zoom only the text on a page. Any daughter pages that reuses the same window/tab will still be zoomed, but if the daughter page is a new window/tab it will be the 100% size. Any new URL page will be at the 100% size.

The Internet Explorer 8 browser also uses the "Ctrl +" and "Ctrl -" keys for zooming in and out. It also has another menu item to just zoom the text on the page, but not the images. Any daughter pages from the zoomed pages are also the new size. Any new URL page will also the zoomed to the current resize. IE6 does not have any shortcuts.
Subtle differences between browsers: When zooming larger you will also notice that the font becomes bold at some point when a single pixel does not suffice to form a character. The larger fonts may take on a different style in different browsers.
When zooming a page the images may zoom at different rate from the font. So some pages will "look" better zoomed in some browsers and worse in other browsers.
Images will also behave differently if they are set to specific sizes. All browsers will up-size and down-size "% images" except Internet Explorer (all versions), which will only up-size images. This is only seen in a few pages on our web site, such as the "Articles & Trip Reports" pages.
Another handy feature is zooming the browser to the full computer screen. The F11 (toggle) key will zoom all browsers to fill your display screen, except Safari. IE8 and Firefox will auto hide the upper tabs, while Chrome and Opera (Windows) only show the page, loosing any tabs. Many web pages now are fixed at 1024 pixels wide, so F11 may not be useful on all pages.
