When the folks at Google reconfigured Blogger some time ago, they omitted the ability to insert html codes. Or at least I thought they had.
It's not that I had ever used many codes, but there a few — very few — that I find handy from time to time — such as the em dash that I just used three times.
Being slow of wit, it took me these many months to figure out that I could still insert them by temporarily reverting to the html mode.
It is rather helpful to be able to use a long dash (em dash) for those somewhat parenthetical comments when parentheses don't seem to be quite right. I had resorted to double dashes (--) but never really fancied them. Now, I have finally figured out that I can temporarily go to the html tab to get this — by typing — (with the semi colon).
Similarly, I can insert a down arrow ↓ by typing ↓ or, similarly, an up arrow ↑ ↑. I find this handy at times when I want to direct people to look up at a photo ↑ or down ↓.
One other symbol that I like to be able to insert is the degree sign by typing ° and getting ° as in 10°C/50°F. It certainly isn't necessary, but it pleases me to be able to do it if I want to.
To do this, I go to the top left of the Blogger editing screen to access the html panel.
But the good folk at Google make it hard because the html panel is one big unseparated wall of text in which it is very difficult to find the point where I want to make the insertion. There used to be spaces and line breaks, but no more; it is one formidable-looking block of letters.
