Disable text drag and drop in browser

I have never in my life got any use out of moving text by drag and dropping of selection inside a textbox. However, it has messed up my texts on numerous occasions, of which I might not have noticed it on every instance. Do you know which wise guy's idea it was to standardize on this?

Ergonomics of the computer mouse and keyboard from a hardware perspective

It's a pretty interesting fact that we still use the not so ergonomic kludges of many decades ago for our daily work. Let's just skip keyboard layouts altogether, as we all know the truth about them! ;-) You see, for technical reasons, ergonomics wasn't considered for these input devices by the original designers. They simply tried to solve the engineering problems of the day - and they have succeeded! They always have two driving forces: one, how similar problems have been solved in the past and two, how to construct a device as simple as possible (i.e., to invent as few things as possible at once). They are initially dominated by the limitations of technology of the day, while later on, they must keep in mind to provide an easy migration path for earlier users of the same or a similar invention ( Wikipedia: Path dependence ). For example, the typewriter has influenced the computer keyboard in all practically possible ways - i.e., they tried to mimic as closely as possibl...

Double clicking is evil

To both a novice and an advanced user, there is no conceptual difference between pressing another button on the mouse and double clicking. Well, actually there is one: you can proceed with superior comfort and greater speed after a bit practicing of the former, while the latter will remain awkward forever. Therefore, it could greatly improve usability if the pointing device had additional buttons to replace this vulgar action. Chording (simultaneously pressing multiple buttons) is also an option. See Wikipedia: Chorded keyboard for more information. As you probably already know, I'm all against any form of double, triple or even quadruple pushing the same button on either the keyboard or the mouse. As a historical note, I'm positive that no human with expert knowledge in the field - or even having any trace of commonsense - would recommend such crippling of ergonomics and usability as banging the same button in succession. I think they have implemented this because the interfa...

One and two handed keyboard layouts

Do you consider intervened keyboard and mouse use ergonomic on your PC? I bet I could give you an exercise that could kill the nerve of one with a two-handed layout! Note that the original designers of the computer mouse and the first graphical user interfaces (that we still mindlessly clone) also had to decide how users ought to handle the two-handed keyboard and the single handed mouse at the same time. They had to choose between either letting the user touch-type two-handed and occasionally withdraw to position the cursor with the mouse, or instructing to use a single-handed keyboard layout that frees the other hand for positioning tasks. They have chosen the former. While it does have its use cases, I don't completely agree with it's dominance. It is pretty versatile, but there may exists scenarios where it would be advantageous to keep one hand on the keyboard and the other on the mouse. Compared to the default method, this one is more ergonomic in applications where you n...
