How to comment multiple lines in Pycharm

If you have a latin keyboard without numpad or any without slash key, maybe you couldn't use the shortcut enabled in Pycharm to comment multiple lines (Ctrl+Slash).
To change this shortcut, you must create a default keymap copy to edit it, just clicking on Copy button.
Go to File/Settings... and write keymap


Now, filter by comment and add a new keystroke, like Shift+3


Enjoy it!

How to fix Android when developer options are not available for this user

Image
I have an Android One with Oreo version and suddenly my Android rebooted and after that it started to behave strangely: 1) Notification section doesn't work. I can't see notifications from my apps and the arrow and the screw icon to settings access don't work. 2) As I can't access to the notification area, I can't enable Use USB to Transfer Files to access to my phone memory. 3) I can't access to developer mode (I before active it with a lot of taps over Build number). Clicking on developer options just shows developer options are not available to this user. 4) I can't update or install the apps on google play. They freeze on Download pending... message 5) Home and Switch buttons don't work. They light up and vibrate when I tap them but they do nothing.
