If you’re using Windows, you could look into Microsoft Powertoys, a suite of cool extensions which adds some nifty functionality.
One of them (I can’t recall its name) allows you to quickly call up a toolbar for special accented characters, and other symbols - eg, if you want the © symbol, you type C, activate the toolbar via a keyboard shortcut and it’s there to select along with ç and other relevant options. I use it all the time, it’s really handy.
EDIT: Here’s a link, and that tool is called Quick Accent
This is maybe not what you’re looking for, as it’s not about growing the money so much as using it to help others, but sharing just in case it’s of interest (no pun intended).

My wife has used this a lot - she reads up on microbusinesses who need a loan to develop, lends small sums (like less than £50 or so) to them and after a while usually gets her money back and then reinvests it in a loan to another microbusiness.
It doesn’t make a profit for the individual lenders as far as I know, but it’s a way to assist people in improving their lives. Kind of cool, I think.
