I like to display invisible characters in my text editors/IDEs because I want to know if the spaces I’m seeing are spaces or tabs. I also like to be able to tell immediately if I’m seeing multiple spaces or not.

Here is an example of what that looks like. Notice the grey dots between words.

In Xcode, you can find this in the Editor menu labeled as Invisibles.

Today I noticed that when using documentation comments, the invisibles are misaligned and lay on top of the characters instead of between them. I submitted a feedback, but I’m not sure it will ever be addressed so I wrote this post in case someone else runs into the same thing.

Use the emoji picker using the function key (🌐) and search for these strings then add to favorites to make them easier to find in the future.

• place of interest → ⌘ [Command]
• option → ⌥ [Option]
• arrowhead → ⌃ [Control]
• upwards white arrow → ⇧ [Shift]
• upwards white arrow from bar → ⇪ [Caps Lock]

I tend not to use tabs and instead have a bunch of windows so I originally wanted to know how I could set my window title bar to show the current path, but in this post I’ll share how to do both in iTerm2.

Here is a screenshot of the iTerm2 Preferences window showing Profiles -> Window.

For custom window title you’ll set \(currentTab.currentSession.path).

For custom tab title you’ll set \(currentSession.path).

And that’s it!

Here’s what it would look like in iTerm2:

And here’s the Stack Overflow question I found that solved this for me. Wanted to blog about it so that I remember how to do this in the future.

I am part of a ton of channels at work and sometimes I need to check them and sometimes I don’t. Normally I scroll through all of them with cmd + K to mark them as read. Today I learned that you can do Shift + Esc to mark all channels as read.
