For example , you push Ctrl+V and insert the buffer content into the window. How can I create my own hotkeys like that? Sorry for noobish question.
Ok...the easiest way, for example On you desktop, you can use accelerated command by right click the icon > properties > shortcut key; Click on the empty space and it will seem like nothing happens, but this is when you assign your "hotkey" I used Shift+1 and whenever I combine Shift+1 Firefox opens.
