Keychron T1 HE trackball: set thumb reach before click depth

If your thumb has to stretch to reach a trackball, faster pointer settings can only do so much. Keychron’s T1 HE gives right-handed users three adjustments to try in order: set where the ball sits, set how fast it moves the pointer, and then set when the main buttons register a click. A few minutes with a familiar task can tell you more about the setup than switching all three at once.

Start with the ball position

The 34 mm ball sits at the thumb side, and the mouse stays put while the ball rolls. Keychron lists three screw adjustments on the underside: 3–3.5 mm side to side, 3–3.5 mm front to back and 2–2.5 mm vertically. These figures describe how far the ball position can change. Set your palm where it naturally rests, then follow the guide and make a small adjustment so your thumb can roll the ball from there. Check that you can select text near both sides of a document without shifting your hand. The adjustment range is small and the shell is right-handed. It’s worth checking your grip before ordering.

Set pointer speed before changing the click

Once the ball is where you want it, leave the screws alone and adjust the pointer speed. Keychron says the on-device DPI button cycles between five presets from 100 to 1,200 DPI. Its Launcher lets you set up to 2,400 DPI. Higher DPI makes the pointer travel farther for the same movement of the ball. Start with a setting that lets you both cross your usual monitor and select a narrow stretch of text. If small targets are hard to land on, bring the speed back down before judging the click settings. Keychron’s DPI note and specifications.

Adjust the point where a click registers

The two main buttons use Keychron’s MagOptic switches. Their optical mode gives you a consistent click response. In magnetic mode Keychron lists twelve trigger-depth settings, so you can choose how far to press before a click registers. Keychron separately specifies the full physical travel at 0.65 mm, plus or minus 0.07 mm. Think of the magnetic setting as choosing a point along that travel. It leaves the thumb ball and pointer speed alone. Use optical mode as a baseline, then try a magnetic setting and repeat the same single click and drag. If you keep clicking as you rest a finger on the button, try a deeper setting. Save Rapid Trigger, which changes when a released button can register another click, for a separate comparison.

A working Bluetooth connection is only the first check

Keychron lists Windows, macOS and Linux support. For its browser-based Launcher, Keychron specifies a USB-C cable or the 2.4 GHz receiver and a current version of Chrome, Opera or Edge. Bluetooth can still move the pointer. If you need to configure click depth on a managed computer, check whether you can use one of the supported browsers and connect by cable or receiver before relying on custom settings.

Check the seller for your postcode

When PING checked on 15 November, Keychron’s international product page showed a US$59.99 preorder and an estimated early-December 2026 dispatch. That is a store estimate, with no confirmed local arrival date. For a UK address, verify the exact T1 HE listing and returns with a retailer before ordering. Keychron’s general international shipping page lists Nigeria, Kenya and South Africa among its exclusions. Its reseller directory separately identifies a South African distributor and retail partners, without confirming T1 HE inventory there.
