Hi All,
Using symbols in C3 is coming up more now so I thought I’d post on the different ways I’ve found to use symbols in Cantabile for notes, rack names, rack and song state names and the rack buttons. There are a number of ways to go. The easiest I find for Windows is the emoji window which can be called up with the key combination " Windows + . " or " Windows + ; " . This brings up the emoji window where you can choose which one to paste. But Paul points out below there are differences between Win 7 and 10 so read his post to get the details.
The next way is the old ALT code method. This is done using the numeric keypad. First you press and hold the Alt key and then enter the Alt code between 0 and 255 to produce a standard or special character. These character codes are listed here
The third type I am familiar with is the Unicode tables method which uses the key combination of press and hold the Alt key then press the plus key on the numeric keypad and then enter the 4 digit hexcode from the tables. The 5 digit hex codes do not type in effectively so copying them is the way to get them. These tables are located here and allow for direct copy to the windows clipboard if you don’t want to use the key sequence.
