Slack Green ブログ

The Slack desktop app gives native notifications, offline reading and every shortcut, and counts input anywhere on the computer for your green dot. Slack in a browser needs no install and adds less memory if your browser is open anyway. The full comparison and which to pick.

Every built-in Slack slash command from Slack's own commands.list, with usage and aliases, plus what the / menu offers for /search, /darkmode and other words that are not commands. /away and /active tested.

The most used mouse jiggler for Windows is the free, open-source Arkane Systems Mouse Jiggler. Install it with winget install ArkaneSystems.MouseJiggler, or unzip the mainline or portable build without admin rights. Its modes, command-line flags, and what it does for Teams and Slack.

Slack's built-in export is for workspace owners and admins. Without admin access you can copy a conversation, print it to PDF from a browser, ask an owner for an export, or use Slackdump, an open-source tool that saves channels and DMs you can see with your own login. Steps, formats, and the policy caveat.

No law bans owning or using a mouse jiggler. The risk is employment, not criminal: breaking a company device policy, or backing paid hours with fake activity, can get you disciplined or fired, as Wells Fargo showed in 2024. Where the risk sits, and what to check first.

On Windows, set closing the lid to Do nothing in Power Options. On a Mac, use clamshell mode: power adapter, external display, keyboard and mouse. Commands for both, the admin and heat caveats, and why Slack still shows you away with the lid closed.

AFK means "away from keyboard". It is text people type, not Slack's away dot. Download free AFK, away and BRB emoji we tested in a real Slack status.

Slack shows you active when you are not because one connection still counts as active: a forgotten tab, another computer, your phone screen, a huddle or an app signed in as you. We measured it with users.getPresence, and show how to find it in Access Logs.

No. A video sends no keyboard or mouse input, and that is what Slack's 10-minute timer needs. We played a YouTube video on a Mac and logged the idle counter and power assertions.

Slack shows "is typing" to people in a conversation while you write. The setting in Preferences, Messages & media hides other people's typing from you, not yours from them. We logged the signal Slack sends: only the channel ID, never your text.

Google Chat stays active for 5 minutes after your last activity in Gmail or Chat on a computer, then shows Idle, and Away after more than 10 minutes. Its status menu has no always-available option. How the status works, what you can set, and what keeps it green.

Microsoft Teams stays on Away (yellow) while you work when you set Appear away or a status duration, when the phone app is in the background, when Teams on the web cannot see activity outside the tab, or when presence is stale. Fix it by resetting your status, closing Teams on other devices, and signing out and in.

PowerToys Awake keeps a Windows PC from sleeping, but it does not keep Slack or Teams active. Slack sets you away 10 minutes after your last keyboard or mouse input and Teams after 5 minutes, awake or not. How Awake works, its modes, and what does keep you green.

You can keep a work computer awake without admin rights: raise the sleep and screen timeouts in Settings, run caffeinate on a Mac, use PowerToys Awake or presentation mode on Windows, or a browser Wake Lock tab. None of them beat an IT lock policy, and none keep Slack or Teams active.

To delete your Slack account, deactivate it in each workspace: go to my.slack.com/account, scroll to Deactivate account, confirm your password, and click Yes, deactivate my account. Your messages stay. What else to know, and how to delete a whole workspace.

Schedule send only sends once. /remind repeats on every plan, but it misread 'every month on the last Friday' in our test. Workflow templates were locked on Free.

Slack uses a lot of memory because the desktop app is Electron, a Chromium browser running Slack's web app, and each workspace, busy channel, GIF and huddle adds to it. Slack engineering measured about 130 MB to 960 MB per workspace. What drives it, and how to cut it.

Slack keeps logging you out when your workspace admin set a session duration, when your browser deletes Slack's cookies, or after a password change or sign out of all sessions. How to tell which one it is, and what you can change yourself.

Copyable /remind commands for channels and yourself, with what Slack set up for each in our test, the month-end phrasings it gets wrong, and how to list and delete reminders.

Slack's presence API is two Web API methods: users.getPresence reads whether a user is active or away, and users.setPresence sets you away or back to auto. Presence changes stream only over RTM. Scopes, rate limits, the fields you get, and working curl and Python code.

The working ways to jiggle the mouse on a Mac: the free Jiggler app, App Store movers, a USB jiggler, and a one-line cliclick script. What each needs, what IT can see, and why a software jiggler may not keep the Slack desktop app green on a Mac.

Microsoft Teams sets you to Away after a few minutes with no keyboard or mouse input, when you lock your computer, and Offline when it sleeps. A manual Available does not stop that. What keeps Teams green, and what only looks like it does.

Slack off at work by taking short, planned breaks after real output, answering small things fast, and removing the signals people notice: a grey Slack dot, slow replies, an empty calendar. What gives breaks away, and what to skip.

No. Slack's away timer is 10 minutes on desktop and has no setting. We checked all 12 Preferences tabs, the admin settings and users.setPresence, and list what you can change.

Yes, in most setups. Software jigglers show up as a running app and as injected input. USB jigglers show up as a second mouse in device logs. All of them leave an activity pattern. What each tool sees, with the queries IT uses.

Slack's Duration menu defaults to Today, so a new status ends at 23:59:59. We measured every option, watched Slack clear statuses a minute early, and tested focus mode.

Slackの通知が来ない原因は、たいてい一時停止、メンションだけの設定、デスクトップにいるあいだスマホの通知を控えるしくみ、ブラウザやOSの許可のどれかです。SlackのWeb版で設定をすべて確かめ、今の表示名で示しました。

左下のプロフィール写真、ステータスを更新する、期間、保存の順です。2026年10月3日にすべての手順を試し、入力した言葉からSlackが選ぶ絵文字と、離席中の切り替えの動きを確かめました。

Slackのおやすみモードは、再開するまですべての通知を止めます。デスクトップとスマホでのオンとオフ、静かな時間のスケジュール、/dndの使い方、それでも通知が届く相手をまとめました。

Slackがすぐ離席中になるのは、タイマーが思ったより短く、キーボードやマウスの入力がないまま10分で切り替わり、さらに3つのよくある出来事がタイマーを飛ばして即座に切り替えるからです。原因ごとに見分け方と直し方があります。
