I don't know what browser you are talking about.
Space is common for scrolling one page down... Shouldn't Back Space key scroll one page up?
There are other things in browser interfaces that bug me more:
- In Chrome/Chromium's text field, if I press Up or Page Up when I am at the top, or Down or Page Down the bottom of a multi-line text field ... the window starts scrolling.
- Firefox is very slow when using multiple tabs or windows, but handles large images well. Chrome is very slow when there are large images, but handles multiple tabs and windows well. This is why I use Chromium and not Firefox right now, but both could be better!
Combination of browser and web pages, which could be fixed in the browser:
- Web pages that map the arrow keys to "page forward"/"page back" in some kind of gallery. The arrow keys are for scrolling the page within the window!
By the way, those galleries should use iframes instead of Javascript-trickery to change images so that the browser's Back button stays valid!
- Web pages that adapt their layouts after loading to the pixel-size of my screen, as if I was browsing full-screen without any window borders. Web pages shouldn't know about how many pixels there are on my screen. You are given a window to play in; That is your sandbox!
- I should be able to tell the browser how many DPI it should assume that the screen has, so that it can map point size to pixel size to make the text as small as I want it. I don't remember if it was Firefox or Opera that had this...
Firefox also had a "minimum font size" setting, so that text like in the post above above wouldn't be unintelligible, like it is in Chromium right now.
