Qwerty

Qwerty, an esoteric programming language designed so you can easily translate other languages into it.
The capitalization and only accepted form of the name is "Qwerty".
==Specification==
Programs are a sequence of commands.
It has a LIFO stack and a tape that is infinite on both sides.
Commands:
Command	Meaning
` 	Reverse the stack
~ 	Put the last item of the stack on top
! 	Print the current tape cell’s matching Unicode character
@ 	Set the nth character of the program to the Unicode character given by the current tape cell, where n is a popped value
# 	Duplicate the top item of the stack
$ 	Push the value at the memory address given by the current tape cell
% 	Set the current tape cell to itself modulo a popped value
^ 	Negate the current tape cell
& 	Pop a value and store it at a memory address given by the current tape cell
* 	Pop a value and multiply the current tape cell by it
( 	Start a comment
) 	End a comment
-	Pop a value and subtract it from the current tape cell
_ 	Subtract 1 from the current tape cell
= 	Jump past the next ] if a popped value is equal to the current tape cell
+	Pop a value and add it to the current tape cell
[ 	Used as a loop marker
{ 	Swap top 2 items of stack
] 	Jump to the matching [
\} 	Set the current tape cell to the length of the stack
\ 	Pop a value and floor divide the current tape cell by it
}	Print numeric value of the current tape cell, and then a space
; 	Push the current tape cell onto the stack, setting the current tape cell to 0
: 	Pop the stack into the current tape cell
‘ 	Add 1 to the current tape cell
“ 	Toggle string mode. In string mode, the characters given are translated into numbers using Unicode and put onto the stack. Also, preceding a character with a \ inserts that literal character
, 	Move the tape left 1
< 	Jump past the next ] if a popped value is greater than the current tape cell
. 	Move the tape right 1
> 	Jump past the next ] if a popped value is greater than the current tape cell
? 	Take input, transform it into numbers using Unicode, push it onto the stack
/a/b/ 	Replace all occurrences of a with b (This is evaluated before the rest of the program)
==Computational Class==
It is Turing-complete because of the following translation from Brainfuck, which is Turing-complete:
Brainfuck 	Translation
Program start	;
+ 	'
- 	"
< 	.
> 	,
[ 	[#=
] 	]
. 	!
, 	?
Note that it can take multiple input characters, but only the first one will be accepted. Also, the cell width is infinite, but that version of brainfuck is still Turing-complete.
==Examples==
Hello, World!: 
"!dlroW ,olleH":![;=:!]
Cat: 
[?`:![;=:!]]
Fibonacci sequence: 
';#[:|#+;`]
99 bottles of beer:
/ps/,`:![;=:!]./'''''';''''*[|"bottles of beer on the wall,
"ps|"bottles of beer.
"ps"Take one down, pass it around,
"ps_|"bottles of beer on the wall.
"ps;#=:]
==Translations==
These are some ways to translate other languages into Qwerty.
Deadfish:
Deadfish	Qwerty
i 	'
d 	_
s 	;#:*
o 	|
==Optional extension commands==
These are some optional extension commands: (Will be extended in the future)
Command	Meaning
≠ 	Immediately followed by a comment, that comment will be put into a new thread, thread #current tape cell value
≈ 	Like ≠ but creates a daemon thread
§ 	Wait until thread #current tape cell value is finished
==Interpreters==
Python 3 (Does not support extension commands yet)
