hopefully english isn’t your primary language, as some of this stuff is hard to cypher. Anyhow, left click has been established as a horrible paradigm. Double click even worse. How many people do you know using a browser that rapidly click endlessly until something happens? I know a bunch. Also, clicking is a major contributor to RSIs. In other words, clicking is pretty much the worst workflow enhancement ever, both physically and operationally. Pretty much every application has gone to advanced keyboard accelerator functions, as these are much, much, much, much more efficient than using a mouse. There are acceptions of course (highlighting blocks of text for example, a mouse is ideal for that). Right mouse context menus are awesome … but they are there to get you to little used operations. There should be an accelerator for every menu item.
Anyhow, click = bad
doubleclick = really bad
