How to move the cursor while typing Khmer on iPhone
To move the cursor in iBoard, slide left or right on the space bar and watch the insertion point in the draft. Stop where you want to edit. You can also tap the text directly or touch and hold near the insertion point and drag it into position.
Choose a spot in the middle of a draft
Open a blank note and switch to iBoard with the globe key. Type a short Khmer line that you can easily reread. For a disposable example, type សៀវភៅថ្មី and imagine you want to add a visible space between សៀវភៅ and ថ្មី.
After typing, the caret is at the end. Aim for the boundary just before ថ្មី. The practice edit should produce សៀវភៅ ថ្មី. The visible space makes the edit easy to verify in this practice note.
Slide on the iBoard space bar
Start your finger on the space bar and slide left to move back through the text. If you pass the intended spot, slide right and watch where the caret stops.
Release your finger and check that the caret is between the two parts before you type. Tap the space bar to insert the practice space, then reread both parts. Keep the note open so you can undo and try again if the space lands inside a word.
Place the caret directly in the text field if needed
Tap near the place you want to edit. Apple also documents touching and holding near the insertion point to magnify it, then dragging it to the intended spot. That can be easier when a short movement lands on either side of the intended boundary.
Place the caret before typing. If the app highlights a selection, tap again and confirm that you see a single insertion point. This lets you insert a character without accidentally replacing highlighted text.
Read the words around the change
Use the visible caret and the surrounding words to judge your position. Khmer spelling can combine signs with base letters, so check the caret after each move to make sure it reached the intended boundary.
Read the word on either side of the change. If a sign looks attached to the wrong word, undo and check the caret position before retrying.
Questions
What if the cursor skips the place I want?
Tap the text field near the spot or use Apple’s magnified insertion point to position it more precisely.
How can I tell whether I will insert text or replace it?
A single caret shows the insertion point. If text is highlighted, clear the selection and confirm the caret is where you want to type.
