Thank you very much. The guy with the beard might be the best teacher I have had. I can fast forward 2X speed, and can understand.

Example (context: mac):
F12 to open devtools `shift+cmd+p` to open command prompt (same shortcut as in vs-code) and search for `screenshot` (its fuzzy search)

Other devtools tips:

devtools `shift+p` lets you search files. Include custom-scripts that you have made (seems one step less than going through the command prompt)

Protips:
* Take care of your hands automate repetitive input; rebind shortcuts you use all the time.

If you want to toggle between the last and current cursor positions in vim, use ‘’ (single quotes pressed twice in normal mode). This uses a predefined mark and it will be a life saver.

Thank you very much. It's worth to learn before you enter your IT life

I thought i would share some of the best vim tips I learned, here are some that I find really useful and convenient:

1. You can enter normal mode in the command line by writing norm followed by whatever command in normal mode(Really useful combined with the other tips I will talk about)

2. If you select a couple of lines and entered command line mode with colon you can apply a command on these lines for example I can select a bunch of lines and go into normal mode and do something like this >> "norm As", Which will append an s in all of those lines, this tip is really powerful if you combine it with macros you can essentially write a macro recorded @y for let's say which wrap a string with parenthesis and then select a bunch of lines and wrap them all with parenthesis which the code for which would look something like this >> "norm @y"

3. the g command in command mode, also another powerful command if you combine with macros it basically let's you find a pattern and execute a command on and the syntax for it looks like this >> %g/pattern/command, notice the % here is just an alias for the whole file, and there really infinite possibilities with this command you could do all sort of crazy stuff with it you can reverse a file and move some lines which follow a specific pattern I would suggest you search and explore with this command

4. YOU CAN WRITE A SHELL COMMAND using vim command mode sorry for caps but I find that really kind of impressive i don't know and the syntax is basically you go into command mode and write !your_shell_command that's it, I would suggest you combine this with the read command in vim so doing something like >> "read !ls" should output all the list of directories in your current path into your file, a good example that I found useful is using the read and the date command in bash would output the date in your folder directly I think that can be pretty useful

every time I think I know vim I keep finding stuff about it that would blow my mind

Can you keep on posting videos? Even as a 15 year old I benefit greatly from this and it has made my projects much easier

I used Gentoo and Sabayon in the past, but now I am enjoying OpenSuse Tumbleweed a lot.

Another reason to use shell scripts over python scripts is portability and speed of composition. Shell scripts can be very fast and compact for simple tasks, but once the task becomes sufficiently complex the expanded power of a real programming language will more than compensate for the more verbose source.
