LineEdit provides a single-line string editor, used for text fields.
|
|
It features many built-in shortcuts which will always be available ([kbd]Ctrl[/kbd] here maps to [kbd]Cmd[/kbd] on macOS):
|
|
- [kbd]Ctrl + C[/kbd]: Copy
|
|
- [kbd]Ctrl + X[/kbd]: Cut
|
|
- [kbd]Ctrl + V[/kbd] or [kbd]Ctrl + Y[/kbd]: Paste/"yank"

|
|
- [kbd]Ctrl + A[/kbd]: Select all text
|
|
- [kbd]Up Arrow[/kbd]/[kbd]Down Arrow[/kbd]: Move the cursor to the beginning/end of the line
|
