+" Vim Keymap file for Russian characters
+" layout English-US standard 104 key 'QWERTY', 'JCUKEN'
+"
+" Maintainer:	Restorer <restorers@users.sourceforge.net>
+" Last Changed: 20 Jan 2019
+" Description:  Раскладка сделана на основе раскладки «русская машинопись»
+" (KBDRU1.DLL), поставляемой в составе ОС MS Windows. Эта раскладка позволяет
+" печать практически все знаки препинания используя цифровой ряд и не требуя при
+" этом нажатия дополнительных клавиш, ну и также удобное расположение буквы «Ё».
+" Однако были внесены некоторые дополнения (улучшения?), в частности:
+" ‐ раздельные символы круглых скобок (), расположены на тех же позициях, что и
+" в US-International;
+" ‐ раздельные символы типографских кавычек «», расположены на клавишах «3» и
+" «4» соответственно;
+" ‐ на этих же клавишах находятся внутренние кавычки “лапки”, набираемые при
+" нажатой клавише «ALT»;
+" ‐ возможность набирать символы, отсутствующие в русской раскладке клавиатуры,
+" а именно @#$^&*{}[]"'`~<>, которые расположены на тех же местах, что и раньше.
+" Для этого не требуется переключаться в латинскую раскладку клавиатуры, а
+" оставаясь в русской, использовать для этого дополнительные клавиши «SHIFT» и
+" «ALT»;
+" ‐ и ещё несколько удобств, которые позволяют быстро и с минимальными усилиями
+" набирать текст.
