Yante is a terminal, mostly the same as xterm, except that it has no pretentious of emulating a VT52/100/220 keyboard.
Leaving the paradigm of emulating a legacy keyboard has several benefits. First, it allows a simple and uniform form of keyboard escape sequences to be used. This means that Yante is less sensible to buggy client programs (such as bash or libreadline) that fail to keep track of the VT100 keyboard state. Second, it allows more precise infomation - all modifier/keysyms can be represented, and an Emacs running inside Yante gets almost as precise keypress events as Emacs running in its own window, even bizarre events like meta-hyper-kp-end. Third, the translation is well-defined, unlike in the xterm family where there are several different ways of mapping X11 keysyms to the virtual VTxxx keys. There is no risk of running into a subtly wrong terminfo description - if the one you get works with Yante at all, it almost certainly does the Right Thing.
