bepo | Custom version of the french dvorak keyboard layout | Keyboard library

I have discovered Vim a year ago and I am getting more and more addicted to it.

I remapped every key of my french dvorak-like bépo layout to stick to the qwerty layout for the normal mode, as described in "Reconfiguration totale des touches" on this page: https://bepo.fr/wiki/Vim, essentially because I learnt with Vim Adventures game.

It works very well:

For instance, yr remaps as cl : the command cuts the character to the right and enter insertion mode.

However, the vim status line displays y for one second before displaying c:

I changed my mapping from:

noremap y c

to this :

map y c

without success.

Anyone knows if it is possible to display a remapped operator-pending key immediately, i.e. "c" in my case ?
