Hi. How are you?
I'll try to help you but you'll have to understand it in english (wahou... You shouldn't "te la peter grave"
)
So, the best way to know the keyboard shortcuts is as following:
Go with your mouse over the menu and when the function appears, you'll have the keyboard shortcut directly written (ie: "select all" = ctrl + "A"). Also, often you can see a letter underligned for each function in the menu. by using ctrl + the letter, it works too (ie: "[/u]C[/u]opy" = ctrl + "C")
Most of the times, if you know the english terms, you do ctrl + the first letter of the term and it works:
ctrl + A = select All
ctrl + C = Copy
ctrl + B = Bold
ctrl + U = underlined
ctrl + I = Italic
........
Also, every computer digit get a unique "ASCII" code. The table can easily be found on internet. It's a 3 digits number. When you press ALT + those 3 digits, you can write every letter or symbol from any language...
Hope everything's clear for ya
