"Why didn't you tell me sooner!" Windows Basic Operations - Text Input Part 1 -
You might use a Windows PC casually every day, but it's actually packed with useful features you might not know about.
I'm posting this in the hope that it reaches those who still don't know these tricks—the kind that make you wish you could get back all the time you spent doing things the hard way before you stumbled upon them.
If you didn't know this, I hope you'll start using it right away to make your future PC life more comfortable.
If you already knew this and have had similar experiences, I'd be happy if you could just shout "I know that feeling!" at your screen.
A method to increase half-width space input efficiency by 300%
Have you ever had a moment where you suddenly needed to input a half-width space while in Japanese input mode?
I used to switch to alphanumeric input mode, type a space, and then switch back to Japanese input mode.
But guess what! I found out it can be done in just one action, so I hope this reaches those who don't know it yet.
How to do it
[ shift ] + [ space bar ]
It's really just that simple!
Prerequisites
Since this is just my personal experience, I will share the prerequisites.
Using Windows 11 or Windows 10
Using Microsoft IME (OS standard) or Google Japanese Input as your Japanese input software
Japanese input software settings are basically at their default installation state
Currently typing in Japanese mode
Looking into it, it seems this method has existed since the DOS/V era in the 1990s, but since I only noticed it a year ago (2025), I don't know exactly when it became available.
If it has been available since the Windows 95 era, it might be worth trying on other OSs and Japanese input software as well.
I haven't used a Mac in a long time and don't have one nearby, so I'm not sure, sorry. (I love Macs, so I'd like to own one if I have the means.)
The reason for 300% input efficiency
When I didn't know this, whenever I wanted to input a half-width space:
[ Half-width/Full-width ] key (switch to alphanumeric input)
Type space bar
[ Half-width/Full-width ] key (switch back to Japanese input)
I was typing.
However, with this method,
[ shift ] + [ space bar ]
it's just one step!
Since the input went from 3 times to 1, is my work efficiency 300%? Someone smart, please tell me.
If you convert it to time, it's only a few seconds per instance, so it doesn't make much of a difference, but I thought that over the course of a year, it would add up to a significant number of times, resulting in huge savings.
I originally used a Macintosh and started using Windows in 2000, so if I had known this method back then, considering how many wasted keystrokes I've made over the 25 years—long enough for a child born then to become an adult and go through two full cycles of the Chinese zodiac—the feeling I had when I first learned it was like wanting to shout "Tell me sooner!" toward a sunset that dyes the beach red.
Me after learning it
I love shortcuts, so I got used to typing [ shift ] + [ space bar ] right away.
Now, I even do it the same way when typing spaces in English mode; it feels a bit strange, but so far there are no issues.
An example where it was good to be able to type spaces during Japanese input without worrying about half-width or full-width
▼ Entering names
Before) Yamada Taro Sama
Now) Yamada Taro Sama
It's just a matter of preference, but I've come to like separating them with a half-width space because the previous input felt too stretched out.
▼ When kanji characters are consecutive
Before) JapaneseInputEfficiency
Now) JapaneseInput Efficiency
Maybe I should just type "Efficiency of Japanese input," but there are times when I want to omit the "no" (of) for context.
In those cases, inserting a half-width space makes the break between kanji subtly!? clear, which I like.
Summary
When you want to enter a half-width space while typing in Japanese,
enter it with [ shift ] + [ space bar ]!
If you think this makes sense, please give it a try.
I've remembered other things that make me want to say "Tell me sooner!", so I think I'll add them leisurely.
If you'd like to try it, or if you already knew it and thought "That's so true," it would encourage me if you could "Like" and "Follow".
Well then, see you in the next article, which shouldn't be too far off!
