The insertion of accentuated characters via Ctrl + x + e for example is very buggy. It does not follow the MS Word system that’s very logical.
On my british keyboard at least, the accent has no connection to the key pressed. For example: Ctrl + ’ + e gives è while Ctrl + # + e gives é that is completely unintuitive while in MS Word: Ctrl + ’ + e gives é and Ctrl + ` + e gives è, i.e. the key used after Ctrl is very representation of the accent to use.
I cound not find a way to get a ñ while my MS Word allows me to simply use Ctrl + ~ + n.
