Ctrl-X is SafeMode. HotMode or “Hotlock” was/is is Ctrl-V. I thought it was removed from V7, but @Chupaka right it’s winbox where it doesn’t work using Ctrl-V (F7 now). But Hotlock does work when you SSH in using Ctrl-V, so it’s just the Winbox terminal where the Ctrl-V isn’t taken.
Edited: another thread had this comment from Mikrotik:
HotLock mode hotkey has been changed too. Now it is F7 (Ctrl-V removed). Winbox Terminal still doesn’t support Ctrl-V, though. You have to press Shift+Ins to paste. But at least now you won’t accidentally activate HotLock mode while trying to paste.
Are those types of changes documented somewhere?https://help.mikrotik.com/docs/display/ > … ListofKeys
