Muscle memory, also known as motor learning, is a form of procedural memory that involves consolidating a specific motor task into memory through repetition. When a movement is repeated over time, a long-term muscle memory is created for that task; eventually allowing it to be performed without conscious effort. This process decreases the need for attention and creates maximum efficiency within the motor and memory systems. Examples of muscle memory are found in many everyday activities that become automatic and improve with practice, such as riding a bicycle or typing on a keyboard or playing video games.
Works fine for me, and I haven't noticed any problems with it with the latest Opera.
The difference is that to do a cmd+a or cmd+c involves two hands (small hands on my part) and to lift up my hands from the mouse whereas right click on a mouse involves just one and no stopping and lifting my hands from the mouse.
<Heretic121> some people need the visual "pointer" when they're doing something
<Heretic121> it's a choice between programming your brain to remember Ctrl+C as copy and Ctrl+V to paste something
<Heretic121> whereas with a right click there is a visual pointer indicating what will happen when (s)he clicks on it
<Heretic121> it's the same with people who prefer CLI over GUI
<Heretic121> CLI denotes a sort of mind that is organised and knows what it's doing
<Heretic121> GUI denotes a sort of "click and pray" mind
