If you are working on a windows environment, you may install and use the Microsoft Keyboard Layout Creator. The idea is to add some key combinations to your current keyboard that will allow you to produce the characters you need, and give a new name to this keyboard. These two videos provide the basics for using the app: https://www.youtube.com/watch?v=nkEUCtqm0uc https://www.youtube.com/watch?v=87bt7GBM02M Here are the codes for some characters you may want to add (other codes may be found here: http://www.utf8-chartable.de/unicode-utf8-table.pl): ¿ = U+00bf ¡ = U+00a1 ´ = U+00B4 (use this. You will type this one and then the character to obtain á, é, ó, ú, í, ) U+0060 (dead key grave accent, use this. You will type this one and then the character to obtain à) ̃ U+0303 (combining tilde., use this. You will need to type the character FIRST and and then this one to obtain things like ã ẽ Ã ) - ^ = U+005E (use this. you will type this one and then the character to obtain â ê,) ¨ U+00a8 (dead key - combining diaeresis, use this. . you will type this one and then the character to obtain ü, etc.) ñ = U+00f1 Ñ = U+00d1 ç = U+00e7 Ç = U+00c7

Perhaps you could install the Spanish language keyboard, and switch to that when typing in Spanish. https://www.windowscentral.com/how-change-your-keyboard-layout-windows-10 This would be your best bet if UK keyboard doesn't otherwise have easy access to the accents and other characters that you'd need. I'm working with a Finnish keyboard which can be "bent to my will" quite easily, minus the upside-down question mark and exclamation mark.

this is probably no help at all (French not Spanish) but just thought I'd mention it anyway... http://french.typeit.org/
