Keyboard Mouse Tricks: Shortcuts & Tips

Keyboard and mouse tricks are the small combinations of keys and clicks that let you navigate, select, and edit faster than pointing and clicking one thing at a time. You get quicker access to common actions, less reliance on menus, and fewer repetitive hand movements. This guide covers the most useful shortcuts for Windows, macOS, and web browsers, plus how to remap buttons and fix common issues.

Formula

The calculator above works out your average pace and speed from a finish time and distance. The formulas are:

• Pace (min/km) = Finish time (min) ÷ Distance (km)
• Speed (km/h) = Distance (km) ÷ (Finish time (min) ÷ 60)

Variables: t is the finish time in minutes, d is the distance in kilometers. Pace is the number of minutes it takes to cover one kilometer; speed is the number of kilometers you cover in one hour.

Worked Example

Using the default values: t = 50 minutes, d = 10 km.

1. Pace = 50 ÷ 10 = 5.00 min/km
2. Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h

The calculator shows an average pace of 5.00 min/km and an average speed of 12.00 km/h.

When to Use This Formula

Runners, cyclists, and walkers use pace and speed to plan training and compare efforts. If you ran a 10 km race in 50 minutes, you now know you held 5:00 per kilometer, which is a common target for club runners. The same math works for any distance: a 5 km run in 30 minutes gives 6:00 min/km and 10 km/h.

How to Read the Result

A lower pace number means faster running (fewer minutes per kilometer). A higher speed number means faster movement. For example, 4:30 min/km is faster than 5:00 min/km. Speed and pace are reciprocals: if you know one, you can compute the other. The calculator gives both so you can use whichever your training plan references.

Common Mistakes

• Mixing units: If you enter distance in miles, the pace will be in min/mile, but the label says min/km. Convert miles to km by multiplying by 1.60934.
• Using seconds instead of minutes: Enter 50 for 50 minutes, not 3000 seconds.
• Rounding too early: If you round pace to 5.0 and then compute speed from that, you get 12.0, but if you keep the full decimal you still get 12.0 for these defaults. For other numbers, rounding early can cause small errors.

Limits of the Formula

This formula assumes constant speed over the whole distance. Real runs include hills, stops, and surges, so the average pace may not reflect how it felt. It also ignores elevation gain, which can make the same pace feel harder. For interval training, you would need separate calculations for each segment.

Frequently Asked Questions

What is a good running pace for a beginner?

There is no single answer because fitness varies widely. A common starting range for a recreational 5 km run is 6:30 to 8:00 min/km (roughly 7.5 to 9.2 km/h). Beginners often run faster than that for short bursts but cannot hold it for the full distance. Use the calculator to find your current average, then aim to improve gradually.

How do I convert pace from min/km to min/mile?

Multiply the pace in min/km by 1.60934. For example, 5:00 min/km becomes about 8:03 min/mile. To go the other way, divide the min/mile pace by 1.60934.

Does the calculator work for walking too?

Yes, the math is the same. Walking pace is usually between 10:00 and 15:00 min/km (4 to 6 km/h). The formula does not care whether you run or walk; it just divides time by distance.

Why does my GPS watch show a different pace?

Most watches use real-time GPS position, which can be noisy, especially under trees or near tall buildings. They also account for pauses if you stop moving. The calculator gives a simple average based on total time and total distance, which matches a race result more closely than a watch’s instant readout.

Can I use this for a half marathon or marathon?

Yes. Enter the total finish time and the full distance (21.0975 km for a half marathon, 42.195 km for a marathon). The calculator will give your average pace and speed for the entire race. That is useful for pacing, but remember that most races are not run at a perfectly even effort.
