Actually PHPStorm is so good with keyboard shortcuts that it offers a few default sets ("keymaps") out of the box to choose from.

Eg. I'm used to Visual Studio shortcuts scheme - I can switch to it straight away (IDE Settings -> Keymap -> Keymaps). There's also Emacs, NetBeans, Eclipse etc. So you don't even need adjusting your habits or wasting time for manual customization.

I don't want to sell you this stuff (not associated with JetBrains in any way), but it's solid, so why make bones about it

As well as being able to set shortcuts for anything you access regularly that doesn't have a default pre-installed, every command can be accessed via one keyboard shortcut (Command + Shift + A on the Mac). You just hit that shortcut, type the first few characters of the command you're interested in, then hit enter.

I switched to PhpStorm from a regular text editor and would not go back.

That is not the idea.

The idea is to use the shortcuts.

Now if I could remember all the shortcuts ...

No need to click on anything. Everything's accessible through the keyboard.
