Translate English into Russian

[GoodUser]

Just translating word by word is good enough.
"capture" means "take screenshot".
The full description of "Left click to capture normally" is "Left click the screenshot button to take screenshot(without hiding the browser window)".
For the word "dial", you can translate it as "item".

Item - in Russian can accept several values, a noun, a verb, an adverb depending on a situation. Therefore there is a question of its application in a concrete situation.
