excel shortcut key with Alt

The 'Alt' shortcuts for the ribbon are hard-coded into Excel, I think. However, there are some ways you can do what you want (or similar).

Firstly, there are often 'Ctrl' shortcuts available for popular commands. In the English version of Excel, 'Insert Hyperlink' (your 'Lien hypertexte') can be accessed using 'Ctrl-K'. There's a list of shortcuts here: https://support.office.com/en-gb/art...9-9b7213f0040f (I don't know if they're all the same in the French Canadian version, sorry, but a web search for 'Touches de fonction et de raccourci d'Excel' should help).

Secondly, you could write (or record) a macro and assign a keyboard shortcut to that. When you record a macro, you get the option to assign a shortcut, starting with 'Ctrl'. If you type an upper case letter like 'X', the dialogue will change from 'Ctrl+' to 'Ctrl+Shift+' - I advise using upper case, as most lower case 'Ctrl' shortcuts are already assigned to something else (as above). If you've already recorded the macro, open the 'Developer' tab, click 'Macros' then on the window that opens, select the macro you want and click 'Options' - you'll then get the same option to assign a shortcut key starting with 'Ctrl'.

Thirdly, you could assign the command you want to your Quick-Access-Toolbar (QAT). If the command is on the ribbon, right-click it and select 'Add to Quick Access Toolbar'. If it's not (or you can't find it, which is a common problem), then click the little down-arrow to the right of the QAT and select 'More Commands'. Find the command you want and click 'Add' - you can move it up or down using the arrow keys at the right-hand side. Once a command is on the QAT, you can activate it using 'Alt' and a number - as you can see in the picture you have in your post. Putting your most commonly used commands at the top of the list (the left of the QAT) means you can access them using 'Alt-1', 'Alt-2' etc, which is quite quick.


I hope that's of some help, even though it doesn't actually do what you asked for .
Almost all of what I've written above uses English terms/labels but hopefully it's not too difficult to work out the French equivalents .

p.s. your profile says you're using Excel 2003, but the picture is 2007 - if you use both, then it's best to say that, so that members here can customise answers to your version.

If you really must replace one of the built-in 'Alt' shortcuts, then I think it might be possible using VBA, using this page as a start: http://www.rondebruin.nl/win/s4/win012.htm
If you have a VBA expert at your company (or you are one yourself) then there might be a way of amending some of the 'Application.OnKey' code to disable the built-in Alt-??? shortcut and replace it with Alt-X. I've tried, but can't get it to work - and I don't know enough about the inner workings of the Excel ribbon to understand why what I've tried doesn't work - but maybe someone with more VBA knowledge than me can work it out. Good luck.
