I typed a short piece of text in GIMP, then I want to fix the kerning manually so I want to move the letters closer to each other. But when I select the "move" tool and click on the appropriate part of the image, I only seem to be able to move the entire layer. How do I select a certain part of the image and move it manually?
Selecting Text Layers in Gimp
Text is represented in an own layer each until we decide to merge layers down. To quickly select a given Layer, or in this case text, I ususally open the "Layers" dialog, accessible from Ctrl + L, or the Windows > Dockable Dialogs menu.
There we can select any layer to then use any available transform tool on it such as Move, Scale, Transform, etc.:
Make a selection float
In case we need to transform or move a selection of an image we can choose Select > Float or press ShiftCtrl + L. The area selected will now float as a new layer over the background. This floating selection can also be transformed as shown below:
