Google users Chrome που χρησιμοποιούν την συντόμευση πληκτρολογίου Ctrl-Shift-Q για κλείσουν το program browser, they will find that it doesn't work in version 70.
If you have downloaded and installed Chrome 70, pressing Ctrl-Shift-Q will prompt you with a prompt on your screen prompting you to press the Alt-F and ξ keys (or Alt-F and X if you have the English version) to exit the program.
Of course, all other exit options continue to work, such as pressing the X at the top right in the main window of the program, or tapping the three lines and then exiting, or right-clicking on the Chrome icon in the taskbar and selecting Exit.
The Ctrl-Shift-Q key combination in Chrome on a desktop computer was simply an exit shortcut. Google changed this shortcut to ATL-F keys (at the same time) and then within 2 seconds you should press the “x” key. The above keys work if you have set your system to Greek keyboard, but they don't work on an English keyboard. "ξ" cannot be replaced with "j" if you are running Chrome in Greek language.
The possible reason for this change They are various user complaints to Google that instead of pressing Ctrl + Shift + Tab to change a tab, the fingers went by mistake on Ctrl + Shift + Q and all tabs were closed.
It is interesting to note that Google did not turn off Ctrl-Shift-W, a keyboard shortcut that closes all open tabs and shuts down Chrome without any warning.
