Yes, ~ in my keyboard is to the right of Ç, which is to the right of L. Also, it is not immediately consumed (as in, if I press ~ once nothing happens, if I press ~ then A it will output Ã, or if I press ~ then spacebar it will output ~).
Pressing my ~ key does not opens the console. Neither does the key below ESC, which for me is the apostrophe and it opens the debug tool instead.
I’m using the 4.7 built from github source, up to Sunday’s (February 15) commits.
