Have you ever made a discovery that blew your mind (in a good way)? Something that quickly solved a nagging problem, or perhaps something that you'd been doing wrong for years?

For me, it was discovering that Ctrl + Backspace deletes an entire word. It completely changed how I type.
I was so excited -- I told everyone I knew, thinking I would change the world ...
Only one person cared. But he still thanks me to this day.
Hopefully yours is better than mine!
I discovered it too! And now I use it a lot. Rather than correcting a mispelled word, I just delete it entirely and re-write it. It's way faster.
Also: CTRL+SHIFT+Left Arrow will select an entire word and CTRL+Left arrow will jump.
Exactly, it means you stay in your typing flow. Before -- after hammering Backspace 12 times to delete a word -- I'd have forgotten what I was actually trying to say.
Also, it's really satisfying to see a typo just disappear, like you're swatting it away.
I love all those entire word select shortcuts. They save so much time.
Psst. Have you tried vim?
Ha! Not for a loooong time. Maybe I'm ready.
What I like most about CTRL + Backspace is that it works all over the place -- from Word to Google Docs. In theory my mum could use it (if she could be bothered).
On the Mac I use for work, in iTerm it deletes the previous letter, same as
^H. In this textarea I'm using to type this reply it does... nothing.That's partially just down to it the oddities of MacOS - a lot of keyboard shortcuts are weird on Mac, like ctrl/alt left and right arrow, or ctrl-R or alt-dot. You have to go through a process of setting it up on a new machine, because most of these are broken out the box.
Ah, I'm not a Mac user, so that's good to know. According to @achu it's ⌘ + Delete on a Mac.
Yeah, that does nothing on mine either :)
Oh dear. This might be why I failed to change the world.
on MacOS its OPTION + DELETE
As I mentioned, that does nothing on my Mac.
On Mac, that's
⌘ + Deletethat does teh whole line. option+delete does a word.
Wow, I didn't know that. I used CTRL + Shift + Left + Backspace 🤦♂️ Thanks for that!
Happy to help!
I love that too, although I too often forget it's there.
I found out that Ctrl + Shift + T opens the windows that you had previously closed. As you go on doing it, it will go back in history sequentially and open the windows you had closed in the same way. I was really excited when I discovered it !
Ah man, I could have done with this one yesterday! Thank you!
When using your internet browser, using CMD + L jumps your focus to the address bar. It's really useful, especially when referencing information within the current tab while typing into the address bar.
On Mac,
Cmd+Lwill take you to the address bar. But beware, if you switch platforms a lot,WindowsKey+Llocks the system and you have to login again to unlock. (On Windows, use Alt + D.)Context, using an external keyboard, the Command and Windows keys are in the same location....
F6 does the same thing!
Awesome, I didn't know this. Will have to give it a try.
I'm becoming a keyboard shortcut nut. It makes talking to normal people quite challenging ...
I used F6 for this.
That dragging the middle mouse button in VSCode lets you add multiple cursors on different lines and/or select just a portion of a text on multiple lines at the same time.
Yeah, that's a nice one. Did you see @peacefullatom 's Visual Studio Productivity post yesterday? Well worth a read.
Here's one more trick. Select portion of text and press Ctrl + Shift + L - this will select all fragments within opened document, this you can edit them all at once 🙃
For me, when writing something -> to select more than one word or line, without dragging the mouse pointer the whole time,
just keep the typing bar on starting point and
click the ending point with a shiftit just changes everything
Did I know this? Honestly, I'm not sure. I'm certainly going to start using it now. Thanks!
Huge thing for me was learning how to put the output from the command line directly to the clipboard without going through an intermediate temp file.
Windows:
some_command | clipMacOS:
some_command | pbcopy(For Linux, I believe
xclipis popular, but I'm not completely sure.)The discovery that I could escape the debugging hell with TDD.

Great link -- that really lays TDD out clearly. It can be a tricky sell sometimes.
Out of interest, was your TDD discovery a lightbulb moment or more of a slow realisation?
A wonderful lightbulb. Up to this day, I don't understand why it is not taught from day 1.
I also don't understand why it's not the standard way of doing code''.
Sure there's no one way of coding, but from a junior perspective, TDD is so structuring.
'' I guess that's because developers darwinism : only those who learned to love debugging survived to become professionals.
It may well come. I have a similar feeling about source control. Who wouldn't want a great whack off undo button from day one?
Navigating the shell command history with the arrow keys, I was so happy when I read a tweet about the Ctrl-r shorcut. It was even better when I found out fzf had a keybinding that does the same thing.
Finding out that you can assign an alias to search engines in Chrome and use tab in the address bar to switch to "search mode" was pretty nice. In combination with Ctrl + L I focus the address bar, type yt, press tab, enter my search term, press enter and Chrome takes me to youtube which then will present the search results :)
That's a nifty trick. I'll give that a whirl!
For me the most recent thing was CTE's (Common Table Expressions), best way to make SQL readable, instead of ugly encapsulation of every sub select you can give it nice names and easy structure.
here an example:
with my_cte as
(
select id, t.* from some.table t where
),
2nd_select as
(
select fk_id as id, t.* from awesome.table t
)
Select * from my_cte a
Inner join 2nd_select b on a.id = b.id
